Abstract
Abstract Apparatus and method for a holographic identification system used to determine the presence and identification of objects with tags and labels placed on persons, articles, goods, merchandise, documents, credit cards, identification cards and the like. The apparatus comprises holographic means for encoding and decoding tags and labels with ordinary incoherent light. The method comprises the steps of holographically encoding tags and labels, attaching labels to objects, and holographically decoding tags and labels wherein the encoding and decoding is done with incoherent light.
