ABSTRACT:
A transparent indicia bearing plastic laminate embodying in one integral portion thereof general information and in firmly bonded relation therewith a second portion incorporating specific data directed to a particular individual and which may be a medical history and a photograph, or as an alternative, product specifications and various other forms of visual data. The novel article of this invention is produced by a minimum number of relatively simple and low-cost steps by locating in one section of a carrier member a portrayal of general information such as organization or corporation identity or the like, and in a second section of the carrier member specific data which may include the individual's medical history and photograph accompanied by a fraud-proof signature, or for other applications, product description and operating data, or if a credit card is the purpose, account number, financial background, photograph and signature. The carrier member is sequentially exposed to a 35 mm. camera at approximately a 25 to 1 reduction ratio, and the pair of microfilm negative frames thus exposed, after conventional processing steps, are laminated to produce a transparent plastic card, thereby eliminating the need for a cardboard backing, typing and substantial equipment and manpower requirements as well as producng an identification card which is tamper-proof and provides a vast store of information data when read in available viewing equipment.
