1. An identification card for a card user comprising:

  • a substrate;

    fingerprint sensing means, carried by the substrate, for sensing information related to a fingerprint;

    memory means internal to said substrate and electrically connected to said fingerprint sensing means, for storing information related to a fingerprint of the card user;

    activation means, electrically connected to said fingerprint sensing means and said internal memory means, for initiating internal storage of the information related to a fingerprint of the card user upon activation thereof for a first time;

    controller means internal to said substrate and responsive to said activation means, for independently programming said internal memory means with the information related to a fingerprint of the card user by generating an internal control signal to initiate transfer of the information related to a fingerprint of the card user to said internal memory means for storage therein, upon activation of said activation means for the first time;

    verification means, electrically connected to said internal memory means, for indicating that the information related to a fingerprint of the card user has been successfully stored in said internal memory means upon activation of said activation means for the first time; and

    authentication means, responsive to said fingerprint sensing means, said internal memory means and said activation means, for comparing information related to a sensed fingerprint with the stored fingerprint information of the card user and for producing an authentication signal if the sensed fingerprint information matches the stored fingerprint information of the card user.
