ABSTRACT:
A verification system for verifying authorized use of a credit or bank card or other identification card. The verification system makes use of an image embossed on or laminated onto a card, and information stored on a magnetic strip or other storage arrangement laminated onto or otherwise affixed to the card. The information stored on the card is related to the image embossed on the card. A card reader reads the image and generates a information defining the image. In addition, the card reader reads the information and compares it to the image signature to determine if they conform. Further use of the card may be based on the degree of comparison between the information read from the card and the image signature.
