Abstract: A method of producing transparent indicia bearing plastic laminated identification cards, comprising storing individualized information on transparent or opaque sheets, or preferably, on a roll of microfilm, storing general information on a second transparent or opaque sheet or, preferably, on a slide displaying each of said portions of information, consecutively exposing adjacent frames of a roll of microfilm in a microfilm camera to each display by re-aiming, particularly by pivoting, said microfilm camera, developing said microfilm, and heat-sealing a pair of thermo-plastic sheets to surround the two frames of developed microfilm.
