ABSTRACT:
A record carrier (e.g., an identification card) of the type containing machine-readable representations of data, wherein the record carrier comprises a substrate, a first pattern of machine-readable indicia applied to one surface of the substrate, and a hologram containing machine-readable data disposed on one surface of the substrate. The information represented by the machine-readable indicia and the machine-readable data are related to one another so as to enable a user to verify the authenticity of the record carrier by comparison of the indicia and the data.
