  • Card identifying method and apparatus
    Patent number: 4783823
    Abstract: A card and a card identifying apparatus. The card is imparted with a predetermined characteristic information in the form of an embossment pattern, a character pattern, a fingerprint pattern, a colored pattern or a combination of selected ones of these patterns, while information corresponding to the predetermined characteristic information is stored in a memory incorporated in the card. Upon insertion of the card into the card identifying apparatus, the latter senses the characteristic information while reading out the corresponding information from the card for collation. When coincidence is found between both information, it is decided that the card is genuine.
