Abstract

The present invention relates to identification documents and smart cards. In one implementation, we provide a contactless smart identification document comprising a first contact layer, a second contact layer, and a carrier layer. The carrier laver is sandwiched in between the first and second contact layers, and the carrier layer includes least a transceiver and electronic circuitry. At least a portion of the first and second contact layers migrate into the carrier layer. This migration helps to secure at least a portion of the transceiver or electronic circuitry to the first and second contact layers,

Claims

1. A contactless smart identification document comprising:

a first contact layer;

a second contact layer;

a carrier layer sandwiched in between the first and second contact layers, the carrier layer including at least a transceiver and electronic circuitry; and

wherein at least a portion of the first contact layer and the second contact layer have migrated into the carrier layer, the migration helping to secure at least a portion of the transceiver or electronic circuitry to the first and second contact layers,

2. The contactless smart identification document of claim 1 wherein the carrier comprises at least one of a scrim and mesh.

3. The contactless smart identification document of claim 1, further comprising a laminate layer covering at least one of the first and second contact layers.

4. The contactless smart identification document of claim 2, wherein the laminate layer further comprises personalized information formed thereon.

5. The contactless smart identification document of claim 1, wherein the electrical circuitry operates to provide at least some smart card functionality.

6. The contactless smart identification document of claim 5, wherein the at least some smart card functionality comprises at least one of data carrier, data manipulation, access control, identification verification, carrying biometric information, and data processing.

7. The contactless smart identification document of claim 1, wherein at least one of the first and second contact layers comprises at least one of a polymer, polycarbonate, an adhesive/polymer/adhesive structure, and a polymer/adhesive structure, polyester, polyester urethane, poly-composite, polystyrene, polybutylene terephthalate (PBT), cellulose ester, polyolefin, polysulfone, polyimide, and polybutylene terephthalate (PBT),

8. A method of manufacturing a contactless smart card comprising:

providing a first contact layer and a second contact layer, the first contact layer comprising a front surface and a back surface, and the second contact layer comprising a front surface and a back surface;

providing a carrier having a top surface and a bottom surface;

combining the first contact layer, second contact layer and carrier to form a multi-layered structure, wherein the carrier comprises an antenna and electronic circuitry therein.

9. The method of claim 8, wherein the carrier comprises scrim and the electronic circuitry provides at least some smart card functionality.

10. The method of claim 8 further comprising the step of applying a coating to at least the front surface of at least one of the first and second layers.

11. The method of claim 10 wherein the coating comprises an adhesive.

12. The method of claim 10 wherein the coating comprises at least one of co-extruded polyurethane (PU), an aliphatic PU-based adhesive, KRTY, polyester, polyester urethane, polyether urethane, polyolefin, poly-composites, thermoplastic adhesives, a hot melt adhesive an ultraviolet-cured adhesive, and a thermally cured adhesive;

13. The method of claim 8 further comprising at least the first contact layer prior to combining the first contact layer, second contact layer, and carrier.

14. The method of claim 8, further comprising laminating at least one of:

a top laminate so as to be in contact with the front surface of the first contact layer, and

and a bottom laminate so as to be in contact with the front surface of the second contact layer.

15. The method of claim 14, wherein the laminate comprises personalized information.

16. The method of claim 8, wherein the carrier further comprises a scrim core comprising electrical circuitry and an antenna.

17. The method of claim 16, wherein the carrier is positioned between the first and second contact layers such that the first and second contact layers migrate into or through the scrim layer.

18. The method of claim 16 wherein the electrical circuitry operates to provide at least some smart card functionality.

19. A method of producing smart identification documents comprising:

providing a scrim core comprising electrical circuitry and an antenna; and

providing the scrim core between a first layer and a second layer.

20. The method of claim 19, wherein the scrim core is positioned between the first and second layers such that the first and second contact layers migrate into or through the scrim core.
