The present invention relates to card readers and, more particularly to a card reader and a mobile payment terminal.
At present, card readers in the market mainly includes a single chip microcomputer (hereinafter referred to as “SCM”), a universal serial bus (hereinafter referred to as “USB”) interface, and a near field communication (hereinafter referred to as “NFC”) antenna. The traditional card readers only can, through wired transmission, read data from a dual interface smart stage card card (a storage card embedded with a contactless smart card) or write data in a dual interface smart stage card card. Due to small volume of the dual interface smart stage card card, an antenna device can't be applied in the card; therefore, a separate dual interface smart stage card card can't interchange data with a contactless card reading terminal wirelessly.
In accordance with an aspect of the present invention, a card reader, which renders a separate dual interface smart stage card card to interchange data with a contactless card reading terminal wirelessly, is provided.
The card reader comprises an NFC antenna, an MCU and a data interface unit (hereinafter referred to as “DIU”). The NFC antenna is connected to a dual interface smart stage card card and is configured for performing data interchange between a contactless card reading terminal and the dual interface smart stage card card. The MCU is connected to the dual interface smart stage card card and is configured to read data from the dual interface smart stage card card or write data in the dual interface smart stage card card. The DIU is connected to the MCU and is configured to establish communication between the MCU and a communication terminal.
In accordance with another aspect of the present invention, a mobile payment terminal is provided and comprises a card reader and a dual interface smart stage card card which is inserted and held in the card reader for storing data. The card reader comprises an NFC antenna, an MCU and a DIU. The NFC antenna is connected to the dual interface smart stage card card and is configured for performing data interchange between a contactless card reading terminal and the dual interface smart stage card card. The MCU is connected to the dual interface smart stage card card and is configured to read data from the dual interface smart stage card card or write data in the dual interface smart stage card card. The DIU is connected to the MCU and is configured to establish communication between the MCU and a communication terminal.
Accordingly, by installing an NFC antenna in the card reader, the dual interface smart stage card card inserted in the card reader can interchange data with a contactless card reading terminal wirelessly in a passive environment.
Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Many aspects of the card reader and the mobile payment terminal can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, the emphasis instead being placed upon clearly illustrating the principles of the present thermal interface material. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
In an embodiment of the present invention, by installing an NFC antenna in the card reader, the dual interface smart stage card card inserted in the card reader can interchange data with a contactless card reading terminal wirelessly in a passive environment.
The card reader 31 comprises an NFC antenna 311, an MCU 312, and a DIU 313.
Advantageously, the dual interface smart stage card card 32 is a MicroSD embedded with a contactless smart card.
The NFC antenna 311 is configured for performing data interchange between the contactless card reading terminal and the dual interface smart stage card card 32. The NFC antenna 311 can be connected to an antenna circuit of the dual interface smart stage card card 32 through the antenna contacts of the dual interface smart stage card card 32, i.e. the ninth pin 9 and the tenth pin 10 in this embodiment. The NFC antenna 311 is printed on a printed circuit board (PCB) of card reader 31, or alternatively, is a separate antenna coil independent of the PCB of card reader 31. The operation frequency band of NFC antenna 311 is advantageously about 13.56 MHz.
The MCU 312 is connected to the dual interface smart stage card card 32 and is configured to read data from dual interface smart stage card card 32 or write data in dual interface smart stage card card 32. In this embodiment, MCU 312 is an SCM.
The DIU 313 is connected to the MCU 312 and, under the control of the MCU 312, interchanges data with a communication terminal provided with data interface unit corresponding to the DIU 313 through the DIU 313. In this embodiment, DIU 313 is a USB interface, and the communication terminal is a personal computer (PC).
The card reader 31 further comprises a socket for the dual interface smart stage card card. The socket is connected to the PCB of the card reader 31 and is configured to hold the dual interface smart stage card card.
The exemplary working process of the mobile payment terminal is described as follows: the user inserts the dual interface smart stage card card 32 in the card reader 31; the mobile payment terminal is connected to the PC through the DIU 313 and the mobile payment terminal serve as a standard USB mass storage device (MSD) on the PC. The application program on the PC communicates with the MCU 312 of the mobile payment terminal through instructions in small computer system interface (SCSI) for wired access to the dual interface smart stage card card 32 to charge the dual interface smart stage card card 32, etc., thereby eliminating the need to charge traditional transportation cards on specific chargers.
The dual interface smart stage card card 32 is inserted and held in the card reader 31 to form a mobile payment terminal. The dual interface smart stage card card 32 is electrically connected to the NFC antenna 311 installed in the card reader 31. In a passive environment, the mobile payment terminal is disposed near the contactless card reading terminal, and the coupling of electric field in the NFC antenna 311 obtains the working power of the dual interface smart stage card card 32. The NFC antenna 311 interchanges data with the contactless card reading terminal to realize contactless mobile payment.
In the embodiment of the present invention, by installing an NFC antenna in the card reader, the dual interface smart stage card card in the card reader can interchange data with a contactless card reading terminal wirelessly in a passive environment, and the card reader can also interact with a storage card through wired transmission through instructions.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
