Abstract
An information bearing credit or identification card in which pieces of a diffraction grating, preferably an embossed hologram, are randomly distributed in a plastic or paper card so that light reflecting therefrom uniquely and visually differentiates the grating and hence the card. The pieces may be mixed in the plastic pig or with the paper prior to rolling or sprinkled in the plastic or other substrate during rolling.
