BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to a mobile terminal providing a payment service and a control method thereof.

2. Background of the Invention

Terminals may be generally classified as mobile/portable terminals or stationary terminals according to their mobility. Mobile terminals may also be classified as handheld terminals or vehicle mounted terminals according to whether or not a user can directly carry the terminal.

Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.

As functions of the terminal become more diversified, the terminal can support more complicated functions such as capturing images or video, reproducing music or video files, playing games, receiving broadcast signals, and the like.

Data (for example, audio, video, image, and the like) is obtained by the input unit 120 and may be analyzed and processed by control unit 180 according to device parameters, user commands, and combinations thereof.

The sensing unit 140 is typically implemented using one or more sensors configured to sense internal information of the mobile terminal, the surrounding environment of the mobile terminal, user information, and the like. For example, in FIG. 1A, the sensing unit 140 is shown having a proximity sensor 141 and an illumination sensor 142. If desired, the sensing unit 140 may alternatively or additionally include other types of sensors or devices, such as a touch sensor, an acceleration sensor, a magnetic sensor, a G-sensor, a gyroscope sensor, a motion sensor, an RGB sensor, an infrared (IR) sensor, a finger scan sensor, a ultrasonic sensor, an optical sensor (for example, camera 121), a microphone 122, a battery gauge, an environment sensor (for example, a barometer, a hygrometer, a thermometer, a radiation detection sensor, a thermal sensor, and a gas sensor, among others), and a chemical sensor (for example, an electronic nose, a health care sensor, a biometric sensor, and the like), to name a few. The mobile terminal 100 may be configured to utilize information obtained from sensing unit 140, and in particular, information obtained from one or more sensors of the sensing unit 140, and combinations thereof.

The output unit 150 is typically configured to output various types of information, such as audio, video, tactile output, and the like. The output unit 150 is shown having a display unit 151, an audio output module 152, a haptic module 153, and an optical output module 154.

The display unit 151 may have an inter-layered structure or an integrated structure with a touch sensor in order to facilitate a touch screen. The touch screen may provide an output interface between the mobile terminal 100 and a user, as well as function as the user input unit 123 which provides an input interface between the mobile terminal 100 and the user.

The interface unit 160 serves as an interface with various types of external devices that can be coupled to the mobile terminal 100. The interface unit 160, for example, may include any of wired or wireless ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, and the like. In some cases, the mobile terminal 100 may perform assorted control functions associated with a connected external device, in response to the external device being connected to the interface unit 160.

The memory 170 is typically implemented to store data to support various functions or features of the mobile terminal 100. For instance, the memory 170 may be configured to store application programs executed in the mobile terminal 100, data or instructions for operations of the mobile terminal 100, and the like. Some of these application programs may be downloaded from an external server via wireless communication. Other application programs may be installed within the mobile terminal 100 at time of manufacturing or shipping, which is typically the case for basic functions of the mobile terminal 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the mobile terminal 100, and executed by the control unit 180 to perform an operation (or function) for the mobile terminal 100.

The control unit 180 typically functions to control overall operation of the mobile terminal 100, in addition to the operations associated with the application programs. The control unit 180 may provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 1A, or activating application programs stored in the memory 170. As one example, the control unit 180 controls some or all of the components illustrated in FIGS. 1A-1C according to the execution of an application program that have been stored in the memory 170.

The power supply unit 190 can be configured to receive external power or provide internal power in order to supply appropriate power required for operating elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, and the battery may be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.

At least some of the above components may operate in a cooperating manner, so as to implement an operation or a control method of a glass type terminal according to various embodiments to be explained later. The operation or the control method of the glass type terminal may be implemented on the glass type terminal by driving at least one application program stored in the memory 170.

Referring still to FIG. 1A, various components depicted in this figure will now be described in more detail.

Regarding the wireless communication unit 110, the broadcast receiving module 111 is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 111 may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels.

The mobile communication module 112 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000(Code Division Multi Access 2000), EV-DO(Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA(High Speed Uplink Packet Access), Long Term Evolution (LTE) , LTE-A(Long Term Evolution-Advanced), and the like).

Examples of wireless signals transmitted and/or received via the mobile communication module 112 include audio call signals, video (telephony) call signals, or various formats of data to support communication of text and multimedia messages.

The wireless Internet module 113 is configured to facilitate wireless Internet access. This module may be internally or externally coupled to the mobile terminal 100. The wireless Internet module 113 may transmit and/or receive wireless signals via communication networks according to wireless Internet technologies.

Examples of such wireless Internet access include Wireless LAN (WLAN), Wireless Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), Worldwide Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), HSUPA(High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A(Long Term Evolution-Advanced), and the like. The wireless Internet module 113 may transmit/receive data according to one or more of such wireless Internet technologies, and other Internet technologies as well.

In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA,HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module 113 performs such wireless Internet access. As such, the Internet module 113 may cooperate with, or function as, the mobile communication module 112.

The short-range communication module 114 is configured to facilitate short-range communications. Suitable technologies for implementing such short-range communications include BLUETOOTH™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless USB(Wireless Universal Serial Bus), and the like. The short-range communication module 114 in general supports wireless communications between the mobile terminal 100 and a wireless communication system, communications between the mobile terminal 100 and another mobile terminal 100, or communications between the mobile terminal and a network where another mobile terminal 100 (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks.

In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the mobile terminal 100 (or otherwise cooperate with the mobile terminal 100). The short-range communication module 114 may sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the control unit 180, for example, may cause transmission of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114. Hence, a user of the wearable device may use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user may answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.

The location information module 115 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 115 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal.

As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite.

As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.

The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.

The microphone 122 is generally implemented to permit audio input to the mobile terminal 100. The audio input can be processed in various manners according to a function being executed in the mobile terminal 100. If desired, the microphone 122 may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.

The user input unit 123 is a component that permits input by a user. Such user input may enable the control unit 180 to control operation of the mobile terminal 100. The user input unit 123 may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the mobile terminal 100, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.

The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The control unit 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.

The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.

The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.

The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like). In general, control unit 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the control unit 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.

A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.

As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.

When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the control unit 180. Accordingly, the control unit 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the control unit 180, the control unit 180, and combinations thereof.

In some embodiments, the control unit 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.

The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.

If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The control unit 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.

The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.

Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.

The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.

In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images.

A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.

The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.

A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the control unit. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.

Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.

The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.

An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.

A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.

The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.

The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.

When the mobile terminal 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.

The memory 170 can store programs to support operations of the control unit 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.

The memory 170 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The mobile terminal 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.

The control unit 180 may typically control the general operations of the mobile terminal 100. For example, the control unit 180 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.

The control unit 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the control unit 180 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.

The power supply unit 190 receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.

The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 160 to which an external charger for supplying power to recharge the battery is electrically connected.

As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.

Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.

Referring now to FIGS. 1B and 10, the mobile terminal 100 is described with reference to a bar-type terminal body. However, the mobile terminal 100 may alternatively be implemented in any of a variety of different configurations. Examples of such configurations include watch-type, clip-type, glasses-type, or as a folder-type, flip-type, slide-type, swing-type, and swivel-type in which two and more bodies are combined with each other in a relatively movable manner, and combinations thereof. Discussion herein will often relate to a particular type of mobile terminal (for example, bar-type, watch-type, glasses-type, and the like). However, such teachings with regard to a particular type of mobile terminal will generally apply to other types of mobile terminals as well.

The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally positioned between the front case 101 and the rear case 102.

The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151a of the display unit 151 may be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.

In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 are externally exposed.

As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121b or an audio output module 152b.

The cases 101, 102, 103 may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal 100 may be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body is formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface.

If desired, the mobile terminal 100 may include a waterproofing unit (not shown) for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.

FIGS. 1B and 1C depict certain components as arranged on the mobile terminal. However, it is to be understood that alternative arrangements are possible and within the teachings of the instant disclosure. Some components may be omitted or rearranged. For example, the first manipulation unit 123a may be located on another surface of the terminal body, and the second audio output module 152b may be located on the side surface of the terminal body.

The display unit 151 outputs information processed in the mobile terminal 100. The display unit 151 may be implemented using one or more suitable display devices. Examples of such suitable display devices include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, an e-ink display, and combinations thereof.

The display unit 151 may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.

The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.

The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window 151a and a display on a rear surface of the window 151a, or a metal wire which is patterned directly on the rear surface of the window 151a. Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.

The display unit 151 may also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see FIG. 1A). Therefore, the touch screen may replace at least some of the functions of the first manipulation unit 123a.

The first audio output module 152a may be implemented in the form of a speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like.

The window 151a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151a and the front case 101). In this case, a hole independently formed to output audio sounds may not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.

The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit 154 to stop the light output.

The first camera 121a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170.

The first and second manipulation units 123a and 123b are examples of the user input unit 123, which may be manipulated by a user to provide input to the mobile terminal 100. The first and second manipulation units 123a and 123b may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123a and 123b may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.

FIG. 1B illustrates the first manipulation unit 123a as a touch key, but possible alternatives include a mechanical key, a push key, a touch key, and combinations thereof.

Input received at the first and second manipulation units 123a and 123b may be used in various ways. For example, the first manipulation unit 123a may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit 123b may be used by the user to provide an input to control a volume level being output from the first or second audio output modules 152a or 152b, to switch to a touch recognition mode of the display unit 151, or the like.

As another example of the user input unit 123, a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152a or 152b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof.

The rear input unit may be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body.

Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123a in the rear input unit. As such, in situations where the first manipulation unit 123a is omitted from the front side, the display unit 151 can have a larger screen.

As a further alternative, the mobile terminal 100 may include a finger scan sensor which scans a user's fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit 151 or implemented in the user input unit 123.

The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.

The interface unit 160 may serve as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.

The second camera 121b is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121a. If desired, second camera 121a may alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown.

The second camera 121b can include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera 121b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.

As shown in FIG. 10, a flash 124 is shown adjacent to the second camera 121b. When an image of a subject is captured with the camera 121b, the flash 124 may illuminate the subject.

As shown in FIG. 1B, the second audio output module 152b can be located on the terminal body. The second audio output module 152b may implement stereophonic sound functions in conjunction with the first audio output module 152a, and may be also used for implementing a speaker phone mode for call communication.

At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.

A power supply unit 190 for supplying power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or detachably coupled to an outside of the terminal body. The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance.

The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.

An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 can also be provided on the mobile terminal 100. As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch may cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen.

Hereinafter, a method for extending a camera function of a mobile terminal having at least one of the aforementioned components will be described with reference to the accompanying drawings.

The user input unit 220 serves to receive information from a user. When information is input through the user input unit 123, the controller 280 may control an operation of the all-in-one card 200a to correspond to the input information. The user input unit 220 may be configured as a mechanical button or a touch button. Meanwhile, the user input unit 220 may perform roles the same as or similar to those of the user input unit 123, and thus, a detail description thereof will be replaced with the description of the user input 123 of FIG. 1A.

The sensing unit 240 serves to detect whether a coil related to a payment machine is present in a vicinity of the all-in-one card 200a. In detail, when the all-in-one card 200a comes into contact with the payment machine (point-of-sale (POS) device), the sensing unit 240 may sense reception of a specific signal (e.g., a reset signal) from the coil of the payment machine. When the sensing unit 240 senses the specific signal, the controller 280 of the all-in-one card 200a may recognize that paying starts, and starts a payment operation.

The display unit 250 may be provided to visually output information. The display unit 250 may form a layered structure with a touch sensor to allow a touch application. Also, the display unit 250 may be an e-paper display (EPD) so as not to affect a thickness of the main body of the all-in-one card 200a.

The IC chip unit 260, which serves to safely store and generate card information, includes one or more modules such as a CPU, a memory, a physical security element (SE), and the like. Information of one or more cards may be safely stored in the IC chip unit 260, and the card information stored in the IC chip unit 260 is configured not to be leaked outwardly. The IC chip unit 260 may be, for example, IC 7816 chip. The IC 7816 chip is a chip storing and generating IC information appropriate for standards. The security element is a module storing an electronic signature, and an electronic signature generation key may be positioned in the security element such that the electronic signature cannot be leaked outwardly.

The magnetic unit 270, which serves to generate a magnetic stripe signal, may be configured as a magnetic band storing magnetic information, configured to include a magnetic record layer as a thin coated film storing magnetic information, or configured as a coil converting a current into magnetism.

The magnetic unit 270 may generate a magnetic stripe signal on the basis of card information of a user programmed magnetic card. That is, the magnetic unit 270 may be provided to generate a magnetic strip signal on the basis of card information selected according to a user request, among a plurality of pieces of card information, rather than being the related art magnetic band storing one magnetic information. In other words, the magnetic unit 270 may generate various magnetic stripe signals.

In order to generate a magnetic stripe signal, the magnetic unit 270 may include a booster. The booster serves to amplify a current signal.

In order to perform payment, the controller 180 may control the aforementioned elements. For example, when one of a plurality of pieces of card information stored in the IC chip unit 260 is selected, the controller 280 may transmit the selected card information to the magnetic unit 270 such that payment may be performed, to transmit a magnetic stripe signal to the outside.

The power supply unit 290 may be provided to supply power to the elements forming the all-in-one card 200a. The power supply unit 190 may include a chargeable battery, and the battery may be an internal battery or a replaceable battery.

The user input unit 220 may be configured as a touch button and may be provided to receive a user input for controlling an operation of the all-in-one card 200a.

The display unit 250 may be disposed in a portion or the entirety of the front side of the all-in-one card 200a to visually output card information of one or more cards stored in the IC chip unit 260. Also, the display unit 250 may form a layered structure with a touch sensor to receive a touch input applied to the display unit 250.

The IC chip unit 260 may be disposed in a partial region of the front side of the all-in-one card 200a and configured to be brought into contact with a contact terminal provided in a payment machine when the all-in-one card 200a is inserted into the payment machine. When the IC chip unit 260 comes into contact with the contact terminal, the payment machine may receive card information from the IC chip unit 260 to perform payment.

The power supply unit 290 may be disposed in a region of the front side of the all-in-one card 200a and contacts an external charge terminal of the all-in-one card 200a to receive power from the external charge terminal.

The magnetic unit 270 may have a magnetic band to generate a magnetic stripe signal when contact the payment machine. Here, the magnetic band may be disposed at one edge of the rear side of the all-in-one card 200a. The magnetic band may be configured as a dynamic coil to generate a magnetic stripe signal of a card selected by the user. That is, the magnetic unit 270 may be configured as a dynamic coil capable of generating various magnetic stripe signals, rather than as a magnetic band storing one magnetic information.

The signature column 221 is a region in which the user writes down a signature therein, to identify the user of the all-in-one card 200a. The user may write down a signature in the signature column 221 using a writing article (e.g., a ballpoint pen).

The QR code 222 may convert information into 2D image and store the same. The QR code 222 may include card loss service center information, card user contact information, and the like.

So far, the all-in-one card 200a has been described. Hereinafter, a payment card according to the present disclosure will be described.

Referring to FIG. 2D, a payment card 200b according to the present disclosure may include an IC chip unit 260.

That is, the payment card 200b according to the present disclosure may be a car including only the IC chip unit 260, like the related art IC card having an IC chip.

Meanwhile, the IC chip unit 260 of the payment card 200b may further include a magnetic applet (MS applet) within the IC chip unit 260, unlike the related art IC card. The magnetic applet refers to a small application program including magnetic information for generating a magnetic stripe signal. The magnetic applet may be stored in a memory of the IC chip unit.

The magnetic information included in the magnetic applet may be information different in each card. Also, the magnetic information may be transferred to a coil so as to be converted into a magnetic stripe signal according to standards.

So far, the card according to the present disclosure has been described.

As mentioned above, the card according to the present disclosure is implemented in the form storing only the magnetic applet on the IC chip unit, thus reducing card manufacturing costs, unlike the related art all-in-one card.

FIG. 3 is a block diagram illustrating a card module related to the present disclosure. FIG. 4A is a conceptual view illustrating a card module, FIG. 4B is an exploded view of the card module of FIG. 4A, and FIG. 4C is a cross-sectional view taken along line A-A′ of FIG. 4A.

Referring to FIG. 3, a card module 300 related to the present disclosure may include a sensing unit 340, an interface unit 360, an IC controller 370, a magnetic unit 350, a microcontroller unit (MCU) 380, and a power supply unit 390.

The sensing unit 340 may be configured as a hall sensor sensing a change in magnetism, a button module physically deformed due to insertion or withdrawal of the card, and a sensor sensing a voltage level, and is not limited to an implementation form.

The interface unit 360 may serve as an interface between the card module 300 and a mobile terminal, between the card module 300 and a charge cradle, and between the card module 300 and a card. For example, the interface unit 360 may include a USB communication port for performing USB communication between the card module 300 and a mobile terminal, an external charge port for supplying power between the card module and a charge cradle, a data port for transmitting and receiving power between the card module 300 and a card, and the like.

A detailed description of the interface 360 will be replaced with the description of FIG. 1A.

The IC controller 370 may be provided to transmit and receive data to and from the IC chip unit 260 provided in the card. The IC controller 370 may include an IC chip connection terminal. The IC chip connection terminal may be, for example, IC 7816. The IC 7816 terminal may check the presence of a magnetic applet in the IC chip unit 260 provided in the card or may receive magnetic information from the IC chip unit 260 provided in the card.

As described above with reference to FIG. 2A, the magnetic unit 350 may convert magnetic information into a magnetic stripe signal and transmit the same to the outside. Here, the magnetic unit 350 may be configured as a dynamic coil capable of converting magnetic information requested by the user into a magnetic stripe signal, rather than a magnetic band storing one magnetic information. The magnetic unit 350 performs an operation similar to that of the magnetic unit of FIG. 2A, and thus, an additional description thereof will be replaced with the description of FIG. 2A.

The microcontroller 380 may control the components forming the card module 300, execute a function using the card module 300. For example, the microcontroller 380 may control the IC controller 370 and check whether a magnetic applet is present in the IC chip unit 260 provided in the card. Also, the microcontroller 380 may inform the mobile terminal 100 about the presence of a magnetic applet through the interface unit 360.

The power supply unit 390 may be provided to supply power to the components forming the card module 300, and may include an internal or external rechargeable battery.

Also, the card module 300 may receive power from a mobile terminal electrically connected thereto. That is, the battery of the card module 300 may be charged with power supplied from the mobile terminal.

To this end, the card module 300 may further include a contact terminal for receiving power from the power supply unit 190 of the mobile terminal. In detail, the power supply unit 190 of the mobile terminal may having a first contact terminal disposed on one side thereof. Also, in the card module 300, a second contact terminal may be positioned in a region facing the first contact terminal such that the second contact terminal is electrically connected with the first contact terminal.

In this case, the card module 300 may receive power from the power supply unit 190 of the mobile terminal through the first and second contact terminals.

Referring to FIG. 4A, the card module 300 may include an accommodation region 301 and a sliding region 302.

The accommodation region 301 may have a receiving space to receive a card. The accommodation region 301 may be installed to overlap at least a portion of the rear side of the main body of the mobile terminal.

Also, the accommodation region 301 may have an opening region such that at least a portion of the card drawn into the accommodation region 301 is exposed. The user may apply external force to the card when the inserted card is drawn out through the opening region.

Also, the accommodation region 301 may include a sensing unit (not shown) for sensing the inserted card. The sensing unit may be implemented as a button, a switch, a magnetic hall sensor, and the like, and is not limited in a configuration thereof.

The sliding region 302 may extend in one direction from the accommodation region 301 and include a circuit board to be electrically connected to one side of the mobile terminal. The circuit board may be connected to a circuit of the mobile terminal to communicate with the mobile terminal or perform controlling through the mobile terminal.

Referring to FIG. 4B, the accommodation region 301 may include a pair of guide rails 303a and 303b protruding from both edges and allowing a card to slide when the card is drawn in, and a mounting part 306 positioned at one end portion of the guide rails 303a and 303b and fixing the card when the card is inserted.

A width of the pair of guide rails 303a and 303 may be equal to a width of the card, or may be slightly greater. The pair of guide rails 303a and 303b may have a recess provided in a central region such that both edges of the card may be inserted into the central portion of the guide rails 303a and 303b.

The mounting portion 306 may be configured to surround one end portion of the card drawn into the accommodation region 301 to fix the one end portion of the card. For example, as illustrated in FIG. 4C, a portion of the mounting portion 306 may protrude to overlap a portion of the card.

Referring to FIG. 4C, contact terminals 304a and 304b included in the IC controller 370 may be positioned in a region facing the IC chip unit 260 of the card drawn in the accommodation region 301.

The contact terminals 304a and 304b of the IC controller 370 may be connected to the circuit board 307 of the card module. The card board 307 may be electrically connected to the circuit board of the mobile terminal through the circuit board of the sliding unit 302. The circuit board of the sliding unit 302 may be electrically connected to the circuit board of the mobile terminal through a USB communication port. As illustrated in FIG. 4C, the accommodation region 301 may further include a coil 305. The coil 305 may be disposed within or outside of the accommodation region 301.

Also, the coil 320 may be disposed in a position farther than the card drawn in the accommodation region 301 with respect to the main body of the mobile terminal. For example, as illustrated in FIG. 4C, the coil 305 may be positioned the farthest position from the main body of the mobile terminal, that is, at the outermost portion of the accommodation region 301. Thus, a magnetic stripe signal transmitted from the coil 305 may be transmitted to the outside, without being interfered with by the card or other circuits.

Meanwhile, the case in which the coil 305 is disposed within or outside of the accommodation region 301 has been described, but the coil 305 may be disposed within or outside of the rear side (e.g., the rear case 102 or the back cover 103, please refer to FIG. 10) of the main body of the mobile terminal. In this case, the coil 305 may be disposed on a region of the rear side of the main body of the mobile terminal not overlapping the accommodation region 301 such that a magnetic stripe signal transmitted from the coil 305 is not interfered with by the card 200.

Hereinafter, a method for providing a payment service in the mobile terminal according to the present disclosure will be described. FIG. 5 is a flow chart illustrating a method of providing a payment service in a mobile terminal related to the present disclosure. FIGS. 6A to 6C are conceptual views illustrating a method of executing a payment service in a mobile terminal related to the present disclosure.

The payment service according to the present disclosure may perform payment using the mobile terminal 100, the card module 300 provided to be electrically connected to the mobile terminal 100, and the card 200 inserted into the card module. Here, the card module 300 may be the device described above with reference to FIG. 3, and the card 200 may be the payment card 200b described above with reference to FIG. 2D or may be a general IC card 200c (please refer to FIG. 11B).

Hereinafter, when a term including both the payment card 200b described above with reference to FIG. 2D and the general IC card 200c is used, reference numeral 200 will be used, and when the cards are differentiated, reference numerals 200b and 200c will be used.

The general IC card 200c refers to a card including a currently distributed IC chip and a card performing payment using an IC chip. In the general IC card 200c, a magnetic applet is not stored in the IC chip, unlike the payment card 200b.

Meanwhile, the card module 300 may be detachably attached to the mobile terminal 100, hereinafter, it is assumed that the card module 300 is electrically connected to one side of the mobile terminal 100.

First, the card module 300 according to the present disclosure may sense whether the card 200 is drawn in the accommodation region 301 (S501).

The card module 300 may sense that the card 200 is drawn in or drawn out from the accommodation region 301 through the sensing unit 340. When the card 200 is drawn in the accommodation region 301, the sensing unit 340 may transmit a notification signal indicating that the card 200 is drawn in, to the microcontroller 380. For example, when a button module provided in the sensing unit 340 is pressed as the card 200 is drawn in, a voltage signal is connected to a ground GND by the button module, and the sensing unit 340 may transmit a notification signal indicating that a voltage is 0 by the ground to the microcontroller 380.

When the notification signal indicating that the card is drawn in is received from the sensing unit 340, the microcontroller 380 may transmit the notification signal to the controller 180 of the mobile terminal 100 (S520).

The microcontroller 380 may inform the mobile terminal 100 that the card 200 is drawn in the accommodation region 302. In detail, the microcontroller 380 may transmit the notification signal indicating the insertion of the card into the mobile terminal 100, through a USB communication port connected to the mobile terminal 100 wiredly.

When the card is drawn in, the controller 180 of the mobile terminal may transmit a request for checking whether there is a magnetic applet on the card to the card module 300 (S530).

When the notification information indicating that the card 200 is drawn in the accommodation region 301 is received from the card module 300, the controller 180 may perform a function related to payment.

Here, the controller 180 may perform in any one of a payment mode in which payment is performed and a payment approval mode in which payment is approved, according to types of the card 200.

Here, the types of the card 200 may be determined according to whether there is a magnetic applet. That is, as illustrated in FIG. 2D, the card 200 may be a first type payment card 200b having a magnetic applet or a second type general IC card 200c without a magnetic applet.

When notification information indicating that the card 200 is drawn in the accommodation region 301 is received from the card module 200, the controller 180 may request the microcontroller 380 of the card module 300 to check whether the card 200 has a magnetic applet in order to check a type of the card.

When the request for checking the presence of the magnetic applet is received, the microcontroller 380 may request the card 200 to check a presence of a magnetic applet (S540).

The microcontroller 380 may control the IC controller 370 to check whether a magnetic applet is present in the IC chip unit 260 of the card 200. The IC controller 370 may access the IC chip unit 260 of the card 200 through an IC chip connection terminal (e.g., IC 7816) to check whether a magnetic applet is present. In detail, the IC controller 370 may check whether a magnetic applet is stored in the IC chip unit 260.

After checking the presence of a magnetic applet, the IC controller 370 may transmit information indicating whether a magnetic applet is present in the card to the microcontroller 380.

The microcontroller 380 may transmit the information indicating whether a magnetic applet is present in the card to the controller 180 of the mobile terminal (S550).

When the presence of a magnetic applet is checked, the microcontroller 380 may transmit information indicating whether a magnetic applet is present in the card to the controller 180 of the mobile terminal 100 through a USB communication port electrically connected to the mobile terminal 100.

In this case, the controller 180 may operate in any one of a payment mode and a payment approval mode on the basis of the presence of a magnetic applet in the card 200 (S560).

In a case in which a magnetic applet is present in the card 200, the controller 180 may operate in the payment mode. That is, in a case in which the card 200 is determined as a first type payment card 200b, the controller 180 may operate in the payment mode.

The payment mode refers to an operational state of the mobile terminal performing a function of transmitting a magnetic stripe signal to the outside, i.e., a payment machine, using the magnetic applet present in the card 200b. That is, the payment mode refers to an operational state of the mobile terminal performing a non-contact type payment by transmitting a magnetic stripe signal within a short range, without bringing the card into contact with the payment machine.

When the controller 180 operates in the payment mode, the controller 180 may execute a payment application previously installed in the mobile terminal. The payment application is an application program executed to operate in the payment mode.

The payment application may be a basic application installed at the initial stage of a factory of the mobile terminal or may be an application downloaded through communication from an open market according to a user selection.

The payment application may provide various functions related to payment. For example, the payment application may provide an authentication function for performing payment, a card registration function, and the like.

Also, the payment application may provide various payment schemes, for example, an NFC payment scheme, a barcode payment scheme, a magnetic stripe transmission (MST) payment scheme, and the like. Here, the NFC payment function may be a function performing payment using NFC, and the MST payment function is a function of performing payment using magnetic information. That is, the MST payment function refers to a function performing payment by converting magnetic information into a magnetic stripe signal and transmitting the same to the outside.

Meanwhile, hereinafter, the case of performing payment according to the MST payment scheme will be described, but the present disclosure is not limited thereto and payment may be performed according to a specific payment scheme selected by the user from among various payment schemes.

As discussed above, in the present disclosure, payment may be performed according to the MST payment scheme by electrically connecting a contact type payment available card to the mobile terminal. Accordingly, the user may perform non-contact type payment using the contact type card.

Specific controlling related to a payment mode will be described with reference to FIGS. 7 to 10.

Meanwhile, if the magnetic applet is not present in the card 200, the controller 180 may operate in a payment approval mode. That is, in a case in which the card 200 is determined as the second type card 200c, the controller 180 may operate in the payment approval mode.

The payment approval mode refers to an operational state of the mobile terminal of approving payment using card information stored in the IC chip unit 260 of the card 200c. That is, in the payment approval mode, the mobile terminal may perform the same role as a payment machine of approving payment using a card.

When the controller 180 operates in the payment approval mode, the controller 180 may execute a payment approval application. The payment approval application is an application program executed to operate in the payment approval mode.

The payment approval application may provide a function of inputting a payment amount for payment approval, a function of inputting a payment item, and a function of communicating with a payment server. The user may input various types of information for payment approval through the payment approval application. Also, the user may be provided with a person-to-person (P2P) payment service between individuals. Here, the P2P refers to a service of performing payment between individuals without passing through a payment machine.

Hereinafter, specific controlling related to the payment approval mode will be described with reference to FIGS. 11A to 13.

Meanwhile, when an electrical connection between the card module and the mobile terminal is released, the controller 180 may stop operation of the payment mode or the payment approval mode. In this case, the controller 180 may stop execution of the payment application or the payment approval application and output a home screen page on the display unit 151.

Or, the controller 180 may output notification information indicating that the electrical connection between the card module and the mobile terminal is released on the display unit 151. Thus, the user may recognize that payment using the card may not be performed any longer.

In the above, the control method of providing a payment service according to the present disclosure has been described. In this manner, the mobile terminal providing a payment service according to the present disclosure may automatically perform an appropriate function related to the card through only an operation of inserting the card by the user. Also, by providing the payment mode and the payment approval mode according to a type of an inserted card, the mobile terminal providing a payment service according to the present disclosure may perform various functions related to payment.

Hereinafter, an operation of the mobile terminal operated in the payment mode and the payment approval mode related to FIG. 5 will be described in detail with reference to FIGS. 6A and 6C.

When a notification signal indicating that a card is drawn in the accommodation region 301 is received from the card module 300, the controller 180 of the mobile terminal 100 according to the present disclosure may execute a payment function.

In detail, as illustrated in (a) of FIG. 6A, when a notification signal indicating that a card is drawn in is received, the controller 180 may output the notification information indicating the insertion of the card on the display unit 151. For example, as illustrated in (b) of FIG. 6A, the controller 180 may output notification information indicating insertion of the card on a pop-up window 600.

Here, the controller 180 may output the pop-up window 600 irrespective of a function currently executed in the mobile terminal. For example, as illustrated in (a) of FIG. 6A, in a state in which a home screen page is displayed on the display unit 151 of the mobile terminal, when a notification signal indicating insertion of the card is received, the controller 180 may output the pop-up window 600 on the home screen page.

The pop-up window 600 may include graphic objects 601 and 602 for determining whether to execute a payment application. When the user selects a graphic object 601 approving execution of the payment application among graphic objects 601 and 602 included in the pop-up window, the payment application may be executed. Also, when the user selects the graphic object 602 rejecting execution of the payment application among the graphic objects 601 and 602 included in the pop-up window 600, the payment application may not be executed.

Meanwhile, in the present disclosure, the payment application may be directly executed without outputting the pop-up window 600.

When the payment application is executed, an execution screen 610 of the payment application may be output on the display unit 151 as illustrated in (c) of FIG. 6A.

Meanwhile, after the insertion of the card 200 is sensed, the controller 180 may determine whether to operate in the payment mode or the payment approval mode on the basis of identification information of the inserted card 200.

To this end, when the insertion of the card 200 is sensed, the controller 180 may receive identification information of the inserted card.

In detail, the controller 180 may request identification information of the card 200 inserted into the card module 300, and receive the identification information from the card module 300.

Thereafter, the controller 180 may compare the received identification information with a plurality of pieces of card information stored in the memory 170. When the received identification information matches the plurality of pieces of card information stored in the memory 170 according to the comparison result, the controller 180 may operate as illustrated in (b) of FIG. 6A.

However, if the received identification information does not match the plurality of pieces of card information stored in the memory 170 according to the comparison result, the controller 180 may output notification information indicating that the card is not identified.

For example, as illustrated in (a) and (b) of FIG. 6B, in a case in which the received identification information does not match the plurality of pieces of card information stored in the memory 170, the controller 180 may display notification information indicating that the card is not identified on the pop-up window 620. Thus, the user may recognize that the current card module currently inserted into the card module is a card of someone else or his or her own card but has not been registered to the mobile terminal.

When insertion of an unidentified card is sensed, the controller 180 may operate i) in the payment approval mode or ii) limits execution of the payment application.

For example, as illustrated in (b) of FIG. 6B, the controller 180 may output graphic objects 621 and 622 for executing the payment approval mode on the pop-up window 620. Thus, the user may approve payment using the unidentified card.

In another example, as illustrated in (a) and (b) of FIG. 6C, when an unidentified card is inserted, the controller 180 may output a pop-up window 630 including notification information for card removal, without executing the payment application. In this case, the user may recognize that a card limited in performing payment is inserted, and remove the card from the card module.

Meanwhile, unlike the above description, when a card is inserted, the controller 180 may operate in any one of the payment mode and the payment approval mode, regardless of checking identification information. That is, checking identification information is a certain step which may be omitted.

Hereinafter, an operation of the payment mode according to the present disclosure will be described. FIGS. 7A and 7B are flow charts illustrating a control method of performing payment in a payment mode in a mobile terminal related to the present disclosure. FIG. 8 is a conceptual view illustrating a method of performing payment in a payment mode related to the present disclosure. FIG. 9 is a flow chart illustrating a control method related to one-time password information in a payment mode in a mobile terminal related to the present disclosure. FIG. 10 is a conceptual view illustrating the control method of FIG. 9.

When it is sensed that a card is inserted into the card module 300, the controller 180 of the mobile terminal 100 according to the present disclosure may operate in any one of the payment mode and the payment approval mode.

Here, as described above with reference to FIG. 5, when a magnetic applet is present in the card 200 inserted into the card module 300, the controller 180 may operate in the payment mode. That is, the card 200 inserted into the card module 300 may be a payment card 200b.

In detail, referring to FIG. 7A, when the controller operates in the payment mode, the controller 180 may execute a payment application according to the payment mode (S710).

When the payment application is executed, the controller 180 may display an execution screen of the payment application on the display unit 151.

When the execution screen of the payment application is displayed, the controller 180 may select a specific card to perform payment among one or more pieces of card information stored in the payment card 200b (S720).

The execution screen of the payment application may include a plurality of card images respectively matched to the plurality of pieces of card information received from the card 200b inserted into the card module 300.

Here, only one of the plurality of card images may be displayed on the execution screen of the payment application and the other card images may be sequentially displayed according to a user's flocking input applied to the displayed card image.

That is, the user may select a specific card image among the plurality of card images through a flicking input. Also, the user may select a plurality of card images through various methods, and this is a design element not limited to the aforementioned method.

When a specific card image among the plurality of card images is selected, the controller 180 may set a card corresponding to the specific card image, as a payment target card.

When the payment target card is set, the controller 180 may request one-time password information from a payment server linked to the card set as the payment target card (S730).

When the payment target card is set, the controller 180 may perform wireless communication with the payment server linked to the card in order to perform payment with the card set as the payment target card.

The payment server is a separately set server which may provide a platform service from a card company or a card manufacturer.

The controller 180 may request one-time password information from the payment server through communication. Here, the one=time password information is password information generated using random numbers randomly generated to perform authentication. The one-time password may be generated according to a user request whenever payment is performed, and once generated, the password information should be used within a predetermined time. That is, when the predetermined time has lapsed, the one-time password information may not be valid. The one-time password information may also be termed a one-time password (OTP).

The controller 180 may transmit the received one-time password information to the card module such that payment may be performed using the received one-time password information (S740).

When the one-time password information is received from the payment server, the controller 180 may transmit the one-time password information to the card module 300 through a USB communication module.

Referring to FIG. 7B, when the one-time password information is received from the controller 180, the card module 300 may transmit the one-time password information to the payment card 200b through the IC controller 370 (S750). Here, the payment card 200b refers to a card inserted into the accommodation region 301 of the card module 300.

The payment card 200b may receive the one-time password information through the IC chip unit 260. The IC chip unit 260 may generate magnetic information using the one-time password information and a magnetic applet stored in the memory of the IC chip unit 260.

The magnetic information is information as a base for conversion into a magnetic stripe signal. The magnetic stripe signal is a signal generated using a principle of recording information using electromotive force generated in an electric line when a magnetic line of a magnetized magnet traverses the electric line.

The magnetic stripe signal reaches the payment machine to generate electromotive force in the payment machine, and the payment machine may read magnetic information included in the magnetic stripe signal on the basis of the generated electromotive force.

When the magnetic information is generated, the payment card 200b may transmit the magnetic information to the card module 300 such that a magnetic stripe signal is generated (S760). Here, the payment card 200b may transmit magnetic information through the IC controller 370 of the card module 300 in contact with the IC chip unit 260.

When the magnetic information is received from the payment card 200b, the microcontroller 380 of the card module 300 may transfer the magnetic information to the magnetic unit 350 such that a magnetic stripe signal is generated.

The magnetic unit 350 may convert the magnetic information into a magnetic stripe signal (S770). In detail, when the magnetic information is received, the magnetic unit 350 may convert the magnetic information into a current signal and a booster may amplify the converted current signal. Thereafter, the coil may convert the current signal amplified by the booster into a magnetic stripe signal.

Meanwhile, in a case in which the magnetic unit 350, specifically, a coil, is present on the rear side of the mobile terminal, the controller 180 may transmit a current to the coil. In this case, the coil present on the rear side of the mobile terminal may generate a magnetic stripe signal.

The magnetic stripe signal may be transmitted to the outside (S780). Here, the controller 180 may supply power required for the card module 300 to generate the magnetic stripe signal, to the card module 300. That is, the card module 300 may amplify the current signal through power supplied from the mobile terminal, and generate the magnetic stripe signal.

That is, in the present disclosure, even though the card is not directly contact the payment machine, the magnetic stripe signal may be transmitted to the payment machine. Also, even an IC card unable to perform magnetic stripe payment may perform magnetic stripe payment through the card module.

So far, the control flow in the payment mode of the present disclosure has been described. Hereinafter, an operational state of the mobile terminal in the payment mode of the present disclosure will be described with reference to the accompanying drawings.

As illustrated in (a) of FIG. 8, when a payment application is executed in the payment mode, the controller 180 may output an execution screen of the payment application on the display unit 151. The execution screen of the payment application may include a first card image 810a, among a plurality of card images, and graphic objects 820a, 820b, 820c, and 820d representing payment schemes.

When a flicking input is applied to the first card image 810a, the controller 180 may output a second card image 810b among the plurality of card images. That is, the user may select a card to perform payment through a flicking input.

In a state in which the second card image 810b is selected, a user request for performing MST payment may be received. Here, the MST payment refers to payment using a magnetic stripe signal. For example, as illustrated in (b) of FIG. 8, the controller 180 may select a graphic object 820b for MST payment.

In this case, the controller 180 may perform user authentication for MST payment. For example, as illustrated in (c) of FIG. 8, the controller may perform user authentication through fingerprint recognition. Here, as the fingerprint method, various known schemes may be used, and this is obvious to a person skilled in the art, and thus, a detailed description thereof will be omitted.

When user authentication through fingerprint recognition is completed, the controller 180 may request one-time password information from the payment server. A description of a follow-up procedure will be replaced with the description of FIGS. 7A and 7B.

Meanwhile, as illustrated in (d) of FIG. 8, when the magnetic stripe signal is being transmitted to the outside, the controller 180 may display a time during which the magnetic stripe signal is transmitted, on the display unit 151. Accordingly, the user may recognize a valid time available for payment. Here, the valid time may match a valid time of one-time password information.

Meanwhile, when payment is not performed within the valid time, the controller 180 may transmit a request for stopping the magnetic stripe signal to the card module 300. Thus, the card module 300 may stop transmission of the magnetic stripe signal.

This will be described in detail with reference to FIGS. 9 and 10. First, the controller 180 may determine whether payment is performed within the valid time (S910).

For example, as illustrated in (a) and (b) of FIG. 10, the controller 180 may display valid time information on the display unit 151.

The controller 180 may receive payment approval information from a payment server within the valid time through communication. Here, when the payment approval information is received within the valid time, the controller 180 may determine that payment has been performed.

Meanwhile, if payment approval information is not received from the payment server within the valid time, the controller 180 may determine that payment has not been performed.

When it is determined that payment has not been performed, the controller 180 may request new one-time password information from the payment server on the basis of a user request (S920). That is, the controller 180 may request new one-time password information from the payment server in order to generate new magnetic information.

For example, as illustrated in (c) of FIG. 10, the controller 180 may display screen information requesting one-time password information on the display unit 151. Thereafter, when a request for new one-time password information is received, the controller 180 may display screen information for performing user authentication on the display unit 151. For example, as illustrated in (d) of FIG. 10, the controller 180 may output screen information for fingerprint recognition.

When user authentication is successful, the controller 180 may request one-time password information from a payment server. Meanwhile, in the present disclosure, user authentication is a certain step which may be omitted.

Thereafter, when new one-time password information is received from the payment server, the controller 180 may transmit the new one-time password information to the card module 300 through a USB communication module (S930).

The microcontroller 380 of the card module 300 may transmit the new one-time password information to the IC chip unit 260 of the card 200, and may receive new magnetic information generated on the basis of the new one-time password information from the card 200.

Thereafter, the microcontroller 380 may transmit new magnetic information to the magnetic unit 350. The magnetic unit 350 may transmit a new magnetic stripe signal outwardly on the basis of the new magnetic information.

In this manner, in the present disclosure, security of performing payment may be strengthened.

In the above, the method of performing payment in the payment mode according to the present disclosure has been described. Thus, the user may perform non-contact type payment using a card available only for contact type payment.

Hereinafter, a payment approval mode according to the present disclosure will be described. FIGS. 11A and 11B are flow charts illustrating a payment approval procedure performed in a payment approval mode in a mobile terminal related to the present disclosure. FIG. 12 is a conceptual view illustrating an en example of approving payment in a payment approval mode in a mobile terminal related to the present disclosure. FIG. 13 is a conceptual view illustrating another example of approving payment in a payment approval mode in a mobile terminal related to the present disclosure.

Referring to FIG. 11A, when a magnetic applet is not present on the card 200, the controller 180 of the mobile terminal according to the present disclosure may operate in the payment approval mode (S1110).

When the controller 180 operates in the payment approval mode, the controller 180 may execute a payment approval application according to the payment approval mode.

When the payment approval application is executed, the controller 180 may display an execution screen of the payment approval application on the display unit 151.

Referring to (a) of FIG. 12, the execution screen of the payment approval application may include input windows for inputting required information in performing payment approval, such as an input window for selecting a payment unit, a payment amount input window, an input window for selecting the number of months of installment, and the like.

When payment approval information is input from the user through the payment approval application, the controller 180 may receive card information from the card module 300. Here, the card information may be information stored in the IC chip unit 260 of the card, which may be an identification number, or the like, of the card.

When the card information is received, the controller 180 may perform payment on the basis of the card information (S1120).

The controller 180 may transmit a payment request to the payment server 400 linked to the card corresponding to the card information on the basis of the card information.

To this end, referring to FIG. 11 B, the controller 180 of the mobile terminal 100 may receive card information (e.g., IC information) from the card 200. In detail, the controller 180 may request card information from the card module 300 and the card module 300 may request card information from the card 200.

In response to the request for card information, the card 200 transmits card information to the card module 300, and the card module 300 may transmit the card information to the controller 180.

Thereafter, the controller 180 may transmit the card information and the payment approval information to the payment server 400 and request payment.

The payment server 400 may determine whether to approve payment on the basis of the card information and the payment approval information. For example, the payment server 400 may compare the card information and the payment approval information and approve payment or reject approval.

When payment is approved, the payment server 400 may transmit payment approval information to the controller 180. In this case, the controller 180 may check that payment has been approved, and informs the user accordingly. For example, as illustrated in (b) of FIG. 12, the controller 180 may display a pop-up window indicating that payment has been completed, on the display unit 151.

However, when payment is not approved, the payment server 400 may transmit approval rejection information to the controller 180. In this case, the controller 180 may check that approval of payment has been rejected, and output notification information indicating the rejection of the approval of payment on the display unit 151.

That is, when the mobile terminal according to the present disclosure operates in the payment approval mode, the mobile terminal may serve as a payment machine through direct communication with the payment server.

Meanwhile, in the payment approval mode, the mobile terminal according to the present disclosure may perform payment through communication with the payment server or may perform p2p type payment. Here, the p2p type payment refers to a scheme in which payment is performed between individuals.

In detail, in the payment approval mode, the controller 180 may transmit payment approval information and card information to the payment server such that a payment amount may be directly transferred to a specific bank account. The payment server 400 may be a server dedicated for p2p payment or may be a server of a card company or a bank.

When the payment server 400 approves payment on the basis of the payment approval information and the card information, the payment server 400 may directly transfer the approved payment amount to a specific band account.

For example, the user may insert a card of someone else, rather than his or her own card, into the accommodation region 301 of the card module. Here, as illustrated in (a) of FIG. 13, when the card information of the card of someone else is received, the controller 180 may receive a payment amount and an account number for p2p payment, and perform user authentication.

For example, as illustrated in (b) of FIG. 13, the controller 180 may display screen information for fingerprint recognition on the display unit 151, for user authentication. The owner of the card may input a fingerprint through the display unit 151.

Thereafter, the controller 180 transmits user authentication information, payment approval information, and card information to the payment server 400. The payment server 400 may approve payment on the basis of the user authentication information, payment approval information, and card information.

In this manner, the user may simply perform p2p payment.

As described above, in the mobile terminal according to the present disclosure, since the card module which can be electrically coupled to the mobile terminal is provided, a card is inserted into the card module, and data related to payment is transmitted to and received from the mobile terminal, whereby non-contact type payment of the card may be performed. Thus, in the present disclosure, non-contact type payment may be performed with the card available for contact type payment even without an additional electronic component.

Also, in the mobile terminal according to the present disclosure, the payment mode and the payment approval mode may be automatically executed according to the presence of a magnetic applet, information required for performing magnetic payment, on the card inserted into the card module. Thus, in the present disclosure, a payment approval service may also be provided together, as well as the payment service using the card inserted into the card module.

In addition, in the mobile terminal according to the present disclosure, since the non-contact type payment is performed even without an additional component on the card, manufacturing cost of the card may be reduced.

The present invention described above may be implemented as a computer-readable code in a medium in which a program is recorded. The computer-readable medium includes any type of recording device in which data that can be read by a computer system is stored. The computer-readable medium may be, for example, a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like. The computer-readable medium also includes implementations in the form of carrier waves (e.g., transmission via the Internet). Also, the computer may include the controller 180 of the terminal. Thus, the foregoing detailed description should not be interpreted limitedly in every aspect and should be considered to be illustrative.
