System for forming picture, alphanumeric and micrographic images on the surface of a plastic card

A system for forming an image on the outer surface of a plastic card and for correlating image data with corresponding alphanumeric data, comprises a data acquisition subsystem shown in FIG. 1, an encoder shown in FIG. 2, an exposure station for scanning an electrophotographic medium in accordance with digital image data generated by the data acquisition system, and a toning station for toning the electrophotographic medium to produce a toner image. The encoder forms identifying information corresponding to the alphanumeric data on the card and provides the encoded card to an image transfer station. At the image transfer station, the toner image on the electrophotographic medium is transferred to a portion of the card through heat and pressure. A protective layer is placed over the fused toner image.
