ABSTRACT:
A high-security identification card is produced in a system in which a photograph from a video camera is converted to digital data and reproduced with high-fidelity on a video display screen. Other images, such as signatures and fingerprints, can be treated in a similar manner using either a video camera or a CCD (charge-coupled device). After processing, the video information is displayed on the screen where it is combined with variable data typed in from a keyboard. The digital data from the terminal is fed into a laser printer that prints the portrait and any desired alphanumeric information on a paper sheet. The paper is then laminated, under heat and pressure, between two sheets of transparent thermoplastic material, at a temperature and pressure sufficient to cause the plastic material to penetrate the interstices between the fibers of the paper card and form a unitary structure that cannot be delaminated without destruction of the identifying data. The digital information is stored in a permanent memory to allow the card to be reproduced later, with or without modifications.
