Abstract

In various embodiments, a chip card module is provided that can have: a chip card module support; a wiring structure that is arranged on the chip card module support; an integrated circuit that is arranged on the chip card module support and is electrically coupled to the wiring structure; a chip card module antenna that is arranged on the chip card module support and is electrically coupled to the wiring structure, and a lighting device that is arranged on the chip card module support and is electrically coupled to the wiring structure.

First claim

The invention claimed is:

1. A chip card module, comprising:
a chip card module carrier;
a wiring structure, which is arranged on the chip card module carrier;
an integrated circuit, which is arranged on the chip card module carrier and is electrically coupled to the wiring structure;
a chip card module antenna, which is arranged on the chip card module carrier and is electrically coupled to the wiring structure;
a lighting device, which is arranged on the chip card module carrier and is electrically coupled to the wiring structure; and
a ring arranged along an edge region of the chip card module carrier, wherein the ring is configured to provide additional mechanical stability to the chip card module.

2. The chip card module as claimed in claim 1 , wherein the chip card module carrier comprises a nonconductive carrier substrate.

3. The chip card module as claimed in claim 1 , wherein the integrated circuit is designed to drive the lighting device.

4. The chip card module as claimed in claim 1 , wherein the lighting device comprises a plurality of discrete illuminants.

5. The chip card module as claimed in claim 1 , wherein the wiring structure and the lighting device are formed integrally with the chip card module carrier.

6. The chip card module as claimed in claim 1 , wherein the chip card module carrier comprises a reinforced region, in which the integrated circuit is arranged.

7. The chip card module as claimed in claim 6 , wherein the reinforced region comprises a material layer having a higher stiffness value than the chip card module carrier.

8. The chip card module as claimed in claim 1 , wherein the chip card module antenna is a coil on an opposite side of the chip card module carrier as the wiring structure and is electrically coupled to the wiring structure through feedthroughs in the chip card module carrier.

9. The chip card module as claimed in claim 1 , wherein a transparent covering layer is arranged above a surface of the chip card module carrier on which the lighting device is arranged.

10. A method for producing a chip card module, comprising:
providing a chip card module carrier;
forming a wiring structure on the chip card module carrier;
forming an integrated circuit on the chip card module carrier, such that the integrated circuit is electrically coupled to the wiring structure;
forming a chip card module antenna on the chip card module carrier, such that the chip card module antenna is electrically coupled to the wiring structure;
forming a lighting device on the chip card module carrier, such that the lighting device is electrically coupled to the wiring structure; and
forming a ring on the chip card module carrier, wherein the ring is arranged along an edge region of the chip card module carrier, wherein the ring is configured to provide additional mechanical stability to the chip card module.

11. The method as claimed in claim 10 , wherein the chip card module carrier is formed from a nonconductive carrier substrate.

12. The method as claimed in claim 10 , wherein forming the lighting device comprises forming a plurality of discrete illuminants.

13. The method as claimed in claim 10 , wherein the wiring structure and the lighting device are embodied integrally with the chip card module carrier.

14. The method as claimed in claim 10 , further comprising: forming a reinforced region on the chip card module carrier, in which the integrated circuit is arranged.

15. The method as claimed in claim 14 , wherein the reinforced region is formed from a material layer having a higher stiffness value than the chip card module carrier.

16. The method as claimed in claim 15 , wherein the material layer is formed on the chip card module carrier between the integrated circuit and the chip card module carrier; and/or wherein the material layer is formed below the integrated circuit on the opposite side of the chip card module carrier relative to the integrated circuit.

17. The method as claimed in claim 10 , further comprising:
forming the antenna in the form of a coil on an opposite side of the chip card module carrier as the wiring structure, said coil being electrically coupled to the wiring structure through feedthroughs in the chip card module carrier.

18. The method as claimed in claim 10 , comprising:
filling a region above the chip card module carrier, which is laterally delimited by the ring, with a covering material.
