Abstract

A coded identification card which includes a core sheet and an outer adherent covering for the core sheet. The core sheet has a given transmissivity to radiant energy of a given frequency and intensity or a given range of frequencies and intensities while preselected coded regions of the core sheet have a transmissivity which differs from that of the remainder of the core sheet. The outer adherent covering for the core sheet has a higher transmissivity to the radiant energy than the lowest transmissivity portion of the core sheet. The outer adherent covering preferably has a transmissivity which obscures the preselected coded regions from view by the naked eye.

Claims

1. A coded identification card comprising:

a metallic core sheet having a given transmissivity to radiant energy of a given frequency and intensity;

said core sheet having pre-selected coded regions in the form of openings in said sheet whose transmissivity differs from that of said core sheet;

said core sheet being clad with a plastic material;

outer plastic sheets formed of a plastic material which is compatible with the plastic cladding on said core sheet;

said outer sheets being laminated to said core sheet, and said plastic cladding on said core sheet and the plastic of said outer sheets extending into said openings as a result of heat and pressure employed in laminating said outer sheets to said core sheet, whereby the bond between said core sheet and said outer sheets is enhanced to provide a stronger identification card.

2. The coded identification card of claim 1 wherein said core sheet is of a smaller dimension than said card, and said outer sheets extend beyond the peripheral edges of the core sheet with the outer sheets being bonded to each other in the region adjacent to the periphery of said card.

3. The coded identification card of claim 1 wherein said core sheet and said card are of a rectangular configuration with said core sheet having openings therein adjacent its corners and the corners of said card, and the plastic from said outer sheets extending into the openings adjacent the corners of the core sheet to strengthen the plastic-to-metal bond in the region of said corners.

4. The identification card of claim 1 wherein said outer sheets have a transmissivity which obscures said pre-selected coded regions from view by the naked eye.

5. The identification card of claim 2 wherein said outer sheets have a transmissivity which obscures said pre-selected coded regions from view by the naked eye.

6. The identification card of claim 3 wherein said outer sheets have a transmissivity which obscures said pre-selected coded regions from view by the naked eye.
