Abstract
Disclosed is a holographic card for storing data in holographic format in accordance with the present invention includes a holographic layer for containing holographic information and a transparent protective layer overlaying the holographic layer. The holographic layer includes at least a first data section with machine readable holographic data. The card also includes a second data section containing either or both presentation or security data. The second data section is preferably included in the holographic layer, but can also be separate therefrom, particularly when non-holographic data is contained therein.
