The system includes a card storing a fingerprint of the authorized card user, a card reader into which the card is inserted, and which reads the fingerprint of the card possessor and a judging means for judging whether a card possessor is an authorized card user based upon the result of a comparison of the fingerprint of the card possessor taken in by the card reader with the fingerprint registered in the card, which judging means can be provided in the card or the card reader.

Abstract: An IC card used for conducting a transfer of information through a connector to a card reading out device is provided with electrode terminals for connection to the outside. A shutter is slidably provided within said card so as to cover said electrode terminals in the usual state. A hole provided at the front portion of said card receives a projection provided at said connector when the projection is inserted into the card. The shutter is retreated when it comes into contact with the projection of the connector thereby to expose said electrode terminals when the card is inserted into the connector.
