ABSTRACT:
A credit card is made with a number of optical fibers sandwiched in the card. Some of the fibers intersect opposite edges of the card in a random fashion and provide a unique code characteristic of the card when light is directed into one edge and detected at the other. When cards are made in quantity, the fiber are added in a random fashion providing a unique code for each card.
