Abstract

The present invention relates to a process for producing a transparent or translucent transaction card having multiple features. An optically recognizable compound may be associated with a portion of the card for blocking infrared radiation and may comprise an infrared ink having nanocrystalline indium tin oxide particles. Moreover, a portion of the transaction card may include a second optically recognizable compound disposed thereon. The second optically recognizable compound may comprise an infrared phthalocyanine dye, an infrared phosphor, and a quantum dot energy transfer compound. The infrared ink may be detected by a sensor found in an ATM or card assembly line.

Claims

a layer that is at least one of translucent and transparent; and

a first infrared blocking compound associated with said layer,

wherein said first infrared blocking compound comprises a quantum dot compound.

2. The card of claim 1, further comprising a second infrared blocking compound associated with said layer.

3. The card of claim 2, wherein said second infrared blocking compound is incorporated into said layer.

4. The card of claim 1, wherein said infrared blocking compound blocks infrared radiation above about 1200 nm.

5. The card of claim 1, wherein said infrared blocking compound blocks infrared radiation from between about 1300 nm to about 2500 nm.

6. The card of claim 1, wherein an ink comprises said quantum dot compound.

7. The card of claim 6, wherein said ink is selected from the group consisting of Au, Ag, and Indium Oxide.

8. The card of claim 1, further comprising a third infrared blocking compound comprises an infrared blocking film comprising a plurality of layers disposed on a substrate, said plurality of layers comprising at least two layers having different refractive indices.

9. The card of claim 1, wherein a third infrared blocking compound comprises at least one of an isotropic dielectric multilayer film and a birefringent dielectric multilayer film.

10. The card of claim 1, wherein said layer has a first surface and a second surface, wherein said first infrared blocking material is a first ink that is printed onto said first surface and a second infrared blocking compound is a second ink that is printed onto said second surface.

11. The card of claim 1, wherein said layer has a first surface and a second surface, wherein said first infrared blocking compound is disposed on said first surface and a second infrared blocking compound is disposed on said second surface.
