Abstract
Abstract Information is recorded in situ on a wallet-size card by disposing laser recordable material in the card, then recording indicia, in situ, on the material with a laser. At least some of the indicia are microscopic eye readable information, with the rest being machine readable information, with the eye readable information being redundant with at least some of the machine readable information. This visually read information is recorded as characters made up of matrices of nonconnected laser recorded spots. The characters may be alphanumeric characters, or the like. The characters are read with an optical magnifier. A laser beam and light detector may be used to read the digital information by scanning the card with the beam.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
74 words
A method for recording information in situ on a card comprising, disposing at least one strip of optical contrast direct-read-after-write laser recording material in a carrier and recording information indicia onto said strip, in situ, by means of a laser, at least some of said information indicia being microscopically eye readable information, the other information being machine readable information, the eye readable information being redundant with at least some of the machine readable information.
Claim 2
Independent Claim
74 words
A method for recording information in situ on a card comprising, disposing at least one strip of optical contrast direct-read-after-write laser recording material in a carrier and recording information indicia onto said strip, in situ, by means of a laser, at least some of said information indicia being microscopically eye readable information, the other information being machine readable information, the eye readable information being redundant with at least some of the machine readable information.
