Abstract:
A strip of optical contrast laser recording material is disposed on the wallet-size card, and has laser written characters recorded thereon. The characters are formed by a plurality of pixels, similar in nature to the dots forming dot matrix characters, except that the pixels themselves are formed of spots. The spots are disposed in a geometric regular array and are usually written one column at a time until a complete pixel is formed. Machine readable and visually readable characters may be combined on a single data strip.
