Abstract
Disclosed is a method of manufacturing multilayer identity cards by electrophotographically reproducing identity information on a card core material and then laminating protective film on both sides of the core material. In preferred embodiments, the core material itself may be made up of several layers with additional security markings thereon. A relief grid image or a hologram can be inserted into the card core prior to lamination. In a further embodiment, after lamination, the identity card blank is photomechanically scanned and positioned in accordance with existing control marks and punched to produce the finished identity card.
