These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed, and this description is intended to include all such aspects and their equivalents.
Various aspects of the disclosure are now described with reference to the drawings, wherein like reference numerals are used to refer to elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to promote a thorough understanding of one or more aspects of the disclosure. It may be evident in some or all instances, however, that any aspects described below can be practiced without adopting the specific design details described below.
Aspects of the disclosure include an access card with a built-in input mechanism, such as for receiving a user input of an identifier code.

More specifically, in one example, a user approaches the access point 106 with the access card 100. When the access card 100 enters the electromagnetic field 112 generated by the access card reader 106, the power from the electromagnetic field 112 energizes the power coil 114 inside of the access card 100. In some aspects, such as when the access card 100 is powered solely by the electromagnetic field 112, the user will then input a identifier code 103 into the input device 102. For example, the input device 102 may be, but is not limited to, one or more virtual or physical buttons, a touch sensitive surface, and/or any other type of mechanism configured to receive information from the user. Further, for example, the identifier code 103 may be any type of data, such as but not limited to a personal identification code, numbers, letters, a pattern, or any combination thereof, that identifies the user to the access card 100. In any case, if the identifier code 103 matches a valid identifier code stored in a memory of the switching circuit 108, then the switching circuit 108 will supply power from the power coil 114 to the communication circuit 104 thereby activating the communication circuit 104 to communicate the access request information 115 to the access point 110. Alternatively, in some cases where the access card 100 includes a battery 120, then the user may enter the identifier code 103 into the input device 102 at any time upon approaching the access point 110. In an further alternative, in some cases where the access card includes the battery 120 and an on/off switch 118, the user may press the on/off switch 118 to connect the battery 120 to the switching circuit 108 and enable the processing of the identifier code 103. In this case, the user may turn off the on/off switch 118 to save power in the battery 120 when the access card 100 is not in use to gain access through the access point 110.
In an aspect, the switching circuit 108 is configured to switch between an open state and a closed state to control the communication circuit 104. When the switching circuit is in the open state, then no power is supplied to the communication circuit 104, e.g., the power coil 114 and/or the battery 120 are disconnected from the communication circuit 104. When the switching circuit 108 is in the closed state, then power is supplied to the communication circuit 104, e.g., from being connected to the power coil 114 and/or the battery 120, to achieve the activated state. For example, the switching circuit 108 includes a switch that remains open until the correct identifier code has been entered.
When the switching circuit 108 is in the closed state, the power coil 114 is configured to convert received energy into electrical power to supply the power to the communication circuit 104. The switching circuit 108 is configured to switch to the closed state in response to the identifier code matching a valid identifier code. The switching circuit 108 further includes a memory 116 configured to store at least the valid identifier code 125.
Alternatively if the identifier code 103 does not match the valid identifier code 125, the switching circuit 108 will maintain the open state and no power will be supplied to the communication circuit 104. In some cases, the user will then reenter another identifier code and when such identifier code matches the valid identifier code 125 stored in the memory 116, the switching circuit 108 will switch to the closed state wherein power will be supplied to the communication circuit 104 and the access card 100 will enter the activated state.
The memory 116 contains at least a valid identifier code. Further, in some cases, the memory 116 is further configured to store additional transaction information associated with the access attempt, such as but not limited to a time of requested access or an access point identifier, and/or logs for valid and invalid input (i.e., passcode or pin) entered by user on the access card at the time of requesting access.
As noted above, in some optional aspects, the access card 100 may include the battery 120 which will store power to be supplied to the switching circuit 108. In a further optional aspect, such as when the battery 120 is a rechargeable battery, the access card 100 includes a charging mechanism 122 configured to supply electric charge to the battery 120. For instance, the charging mechanism 122 may include, but is not limited to, an inductive charging device or a universal serial bus (USB) charging port.
In some optional aspects, the access card 100 may additionally include an indicator 124 configured to generate a plurality of different indications to identify a plurality of different access card states. The plurality of different access card states may include at least some of a card powered on state, a card powered off state, a valid identifier code received state, an invalid identifier code received state, a battery level state, a battery full state, or a batter low state. One example of the indicator 124 includes a lighting device configured to generate a light indication (e.g., different colors and/or patterns of light), however, other indicator devices or mechanisms may be used, such as but not limited to an audio device to generate a sound indication or a haptic device to generate a kinesthetic indication.

At block 602, the method 600 includes receiving a user input of an identifier code in at least one input area of a user input device on an access card, wherein the access card is mobile. For example, in an aspect, access card 100, processor 505, memory 515, access card control component 517, and/or receiving component 520 may be configured to or may comprise means for receiving a user input of an identifier code in at least one input area of a user input device on an access card, wherein the access card is mobile.
For example, the receiving at block 602 may include receiving an identifier code through the user input device 102 of the access card 100 as described above. There are multiple methods by which the receiving at block 602 may be performed. The methods of receiving a user input may include by are not limited to receiving a user input (e.g., pressing) of a physical button, receiving a user input (e.g., touch) of a virtual button on a touch-sensitive display, receiving a user input (e.g., touch and motion) in the form of a character and/or number on a touch-sensitive display, or receiving a user input of biometric info such as a fingerprint on fingerprint reader, an iris scan on iris reader, or a voice signal into a microphone.
Further, for example, the receiving at block 602 may be performed via the input device 102 physically located on the access card 100 because physical contact with a common reader or key pad located on or near an access point raises numerous issues. For example, one issue is that many users touching the same reader or key pad numerous times facilitates the spreading of infection and disease. Having a user perform any of the methods described above at a user input device 102 located on a personal access card 100 prevents multiple users from touching any one specific reader or key pad and in turn prevents the spread of infection and disease.
At block 604, the method 600 includes operating a switching circuit on the access card to switch to a closed state in response to the identifier code matching a valid identifier code, wherein the switching circuit is configured to switch between the open state and a closed state, wherein in the open state no power is supplied by the switching circuit, and in the closed state the power is supplied by the switching circuit. For example, in an aspect, access card 100, processor 505, memory 515, access card control component 517, and/or operating component 525 may be configured to or may comprise means for operating a switching circuit on the access card to switch to a closed state in response to the identifier code matching a valid identifier code, wherein the switching circuit is configured to switch between the open state and a closed state, wherein in the open state no power is supplied by the switching circuit, and in the closed state the power is supplied by the switching circuit.
For example, the operating of the switching circuit at block 604 may include a physical circuit wherein when the card is in the idle state, or not being used, a switch within the switching circuit is open and power is not supplied to the communication circuit 104 as discussed above. Further the switch will also remain in the open position when an incorrect code has been entered, before the user has started entering the code, and while the user is entering the code. When the used correctly enters the valid identified code the switch will move to the closed position, which completes the circuit and in turn supplies power to the communication circuit 104.
Further, for example, the operating of the switching circuit at block 604 may be performed in this manner as this is a simple and efficient way to allow an access card to be activated to access an access point when a correct identifier code has been entered. Additionally a simple switching circuit mechanism which closes in response to a correct identifier code being entered may easily be fit into a small access card which can be carried around by a user.
At block 606, the method 600 includes activating a communication circuit, based on receiving the power from the switching circuit, to wirelessly communicate a card identifier of the access card to an access point. For example, in an aspect, access card 100, processor 505, memory 515, access card control component 517, and/or activating component 530 may be configured to or may comprise means for activating a communication circuit, based on receiving the power from the switching circuit, to wirelessly communicate a card identifier of the access card to an access point.
For example, the activating of the communication circuit at block 606 may include activating a microchip, which contains the card number and any other unique data which it can communicate with an access card reader at an access point only after entering a correct or valid identifier code. This communication circuit microchip is connected to the switching circuit such that when the switching circuit is in the closed position, as discussed above, the microchip will receive power and will therefore be able to relay the stored information and in turn may allow the user access to the access point. A microchip is particularly advantageous as it can easily by connected to the switching circuit and can readily fit into a small access card, while still allowing the storage of all of the necessary information required to enter one or a multitude of access points.
In an aspect, the method 600 may further include configuring the switching circuit to maintain the open state in response to the identifier code not matching the valid identifier code. As discussed in more detail above this prevents a person who may find an access card from entering a restricted access point as they must also know the correct identifier code in order to cause the card to transmit the card identifier and gain access to the restricted access point. For example, if a person drops their access card another person would need to enter the correct identifier code for the switching circuit to enter the closed position and for the communication circuit to activate and allow access to an access point.
In an aspect, the method 600 may further include converting, by a power coil of the access card, received energy into electrical power to supply the power to the communication circuit when the switching circuit is in the closed state. In an example implementation, as mentioned above, the access card reader will generate a field, which will activate the power coil when the access card 100 is within range of the access card reader at the access point 110 and will allow the user to enter the identifier code.
In an aspect, the method 600 may further include generating, by an indicator on the access card, an indication that indicates an invalid identifier code has been received. As discussed in further detail above, the indicator may be used to show or otherwise output various states of the access card 100, such as on or off, as well as to relay whether a correct or incorrect identifier code has been entered.
In an aspect, the method 600 may further include receiving a user power input at a power switch to turn on the access card 100 prior to receiving the user input of the identifier code. In an aspect, this may include a power button, which the user may manually switch, however in alternative aspects the access card 100 may turn on automatically when the card is within range of the card read, the access card 100 may turn on in response to significant motion, e.g., as detected by an inertial measurement unit and communicated to the switching circuit 108, such as the user taking out the access card 100 to use it, or the access card may turn on when in the presence of a light source, e.g., as detected by a light sensor and communicated to the switching circuit 108.
In an aspect, the method 600 may further include generating, by an indicator, one of a plurality of different indications to identify one of a plurality of different access card states. In an aspect, the plurality of different access card states comprise at least two of a card powered on state, a card powered off state, a valid identifier code received state, an invalid identifier code received state, a battery level state, a battery full state, or a batter low state.
In an aspect, the method 600 may further include storing, by a memory in communication with the switching circuit, at least the valid identifier code. This will allow control logic in the switching circuit to move the switching circuit between the open and closed states based on whether the identifier code entered matches an identifier code stored within the memory. This allows for all of the necessary information to enter an access point 106 to be stored within the access card 100.
