Abstract
A process for validating an identification badge for a plurality of predetermined periods of time. The process includes generating, preferably randomly, an initial image for an initial predetermined period of time and then transmitting this initial image to a heat transfer printing device. The heat transfer device prints the image on the identification badge to thereby validate the badge for the initial predetermined period of time. Subsequently, a subsequent image is randomly generated for a subsequent predetermined period of time. This subsequent image is then transmitted to the heat transfer printing device. The device subsequently prints the subsequent image on the identification badge to overlay the initial image, thereby concealing such initial image and validating the badge for the subsequent predetermined period of time. A novel heat transfer ribbon is also provided.
