System for identifying card owners uses a card inserted in a data detection device to identify an owner with a finger print image or stored finger print ID data with a finger print sensor to detect a finger print or ID data for a finger.

摘要

When inserted in a data detection device (3), a card (1) identifies an owner with an image of one or more finger prints (2) and/or stored ID data for one or more finger prints. A finger print sensor (4) detects a finger print (2a) or ID data for a finger, information on which is stored on the card. A unit then compares the data detected by the finger print sensor with that on the card.
