A reading unit supplies card information that has been read from a card to a management unit by way of a read-out unit. The management unit assigns a high order of priority to card information that has been newly read and stores the card information to which this order of priority has been given in a memory unit. A fingerprint scanner supplies input fingerprint information to a selection unit by way of a generation unit. The selection unit, upon receiving the input fingerprint information, supplies this input fingerprint information to a collation unit and further, selects a plurality of items of registered fingerprint information that are stored in the memory unit starting in order with items having the highest order of priority. The collation unit, upon receiving the input fingerprint information, collates this input fingerprint information with the registered fingerprint information in the order selected by the selection unit, and determines whether registered fingerprint information that matches the input fingerprint information is present within the plurality of items of registered fingerprint information.
