ABSTRACT:
There is disclosed a novel identification card, sensor, and system using fingerprint or thumbprint pattern identification to confirm the user's identity. The preferred embodiment of identification card contains a sliding transparent window which is concealed when the card is not in use. When the card is used, it is inserted into a sensor and the window is slide to a visible position where the user can impress his or her thumbprint or fingerprint thereon. The sensor scans the thumbprint or fingerprint and transmits the pattern to a central file for comparison with a record thumbprint or fingerprint of the individual who is authorized to use the identification card. An account number can be located on the card enabling the sensor to scan and transmit to the central file, information to identify the record thumbprint or fingerprint against which the user's physical thumbprint or fingerprint is being compared. The authorized user is confirmed by an appropriate indication at the sensor while an unauthorized user is detected by another appropriate indication. Once the authorized user's identity has been confirmed, the transaction is completed; then the transparent window is returned to its concealed position. As the window is being slid to its concealed position, a wiper within the card wipes the residual print from the window. The sensor is particularly convenient for use and includes a compact scanning device and also a keyboard for entry of additional information relating to the transaction.
