  • Patent number: 11210493
    Abstract: A fingerprint recognition card is provided to perform authentication and security functions by recognizing a fingerprint of a user and includes a fingerprint recognition unit configured to detect a fingerprint of a user, a control unit configured to perform registration authentication for the detected fingerprint of the user, a communication unit configured to perform tagging to an external reader depending on the registration authentication of the control unit, and an inductive current generator configured to generate an inductive current in response to approaching the external reader. The inductive current generator generates the inductive current when a distance to the external reader is within a predetermined distance, converts the generated inductive current to a direct current (DC), and supplies the output voltage, which is generated by reducing the input voltage of the converted DC, to the fingerprint recognition unit, the control unit, and the communication unit.
