Abstract
Abstract The card has means for protection against forgery and unauthorized use, and comprises a laminated structure consisting of an outer base layer, an intermediate layer and an outer cover layer. The base layer is a supporting layer of relatively thick transparent foil material providing the necessary durability, rigidity and a portion of the desired thickness of the card. The intermediate layer comprises special paper having zones of respectively different thickness distributed therein and discernable by visual and tactile inspection, and containing security and authenticity features such as water marks, colored threads and the like. The outer cover layer is a covering of transparent material sufficiently thin to conform to the different thicknesses of the intermediate layer, whereby the different thicknesses are accurately reproduced in the outer surface of the outer cover layer. The security and authenticity features may be embedded in the thickened portions of the intermediate layer.
