Abstract

A portable dual-interface data carrier contains a metal sheet which can be provided with low technical effort and especially no ferrite material is required. The resulting portable dual-interface data carrier is more heavy than a state of the art PVC smart card and provides contact based interface on one side, whereas contactless interfaces is working from both sides of the card. One application domain of the data carrier is to provide a so-called smartcard. The present invention is furthermore directed towards a dual-interface module as well as towards a method for providing a portable dual-interface data carrier. Moreover, a data carrier is suggested comprising instructions for performing the suggested method and for manufacturing the portable dual-interface data carrier.

Claims

1. A method for providing a portable dual-interface data carrier, the method comprising the steps of:

forming a metal layer comprising a recess at least of a size of a carrier foil holding an antenna;

attaching the carrier foil holding the antenna to a first plastic layer at a position of the recess;

inserting the carrier foil holding the antenna into the recess; and

forming at least a part of a body of the data carrier by forming a second plastic layer such that the metal layer is arranged between the first plastic layer and the second plastic layer.

2. A computer program product being arranged to perform a method in accordance with claim 1, when being executed on a computer.

3. A method for providing a portable dual-interface data carrier, the method comprising:

providing a metal layer comprising a recess at least of a size of a carrier foil holding an antenna;

introducing the carrier foil into the recess of the metal layer;

attaching a first plastic layer to a first side of the metal layer;

forming at least a part of a body of the data carrier by attaching a second plastic layer to a second side of the metal layer, the second side of the metal layer being opposite from the first side of the metal layer, such that the metal layer is arranged between the first plastic layer and the second plastic layer.

4. The method according to claim 3, wherein introducing the carrier foil into the recess includes attaching the carrier foil to the first plastic layer at a position where the recess of the metal layer is to be positioned.

5. The method according to claim 4, wherein the carrier foil is attached to the first plastic layer such that the carrier foil and the antenna are fixed to the first plastic layer.

6. The method according to claim 4, wherein the carrier foil is first attached to the first plastic layer such that the carrier foil is fixed to the plastic layer without the antenna.

7. The method according to claim 3, wherein introducing the carrier foil into the recess includes inserting the carrier foil into the recess in liquid form.

8. The method according to claim 7, wherein the antenna is provided on top of the carrier foil.

9. The method according to claim 7, wherein introducing the carrier foil into the recess includes inserting the carrier foil and subsequently attaching the carrier foil to the first plastic layer.

10. The method according to claim 7, further comprising curing the carrier foil.

11. The method according to claim 3, wherein the metal layer comprises a first metal layer and a second metal layer.

12. The method according to claim 3, wherein the first plastic layer and/or the second plastic layer includes at least one transparent foil.

13. The method according to claim 3, wherein the first plastic layer and/or the second plastic layer includes at least one opaque foil.

14. The method according to claim 3, wherein the first plastic layer and/or the second plastic layer includes several plastic layers.

15. The method according to claim 3, wherein the carrier foil has a thickness at least as thick or greater than a thickness of the metal layer.

16. The method according to claim 3, wherein the size of the carrier foil holding the antenna is smaller than the size of the recess such that a gap is provided, and

wherein said method further comprises filling said gap with a filling material.

17. The method according to claim 3, wherein the data carrier is provided such that the data carrier does not include ferrite material.

18. A method of making a portable dual-interface data carrier, the method comprising:

providing a metal layer comprising a recess at least of a size of a carrier foil holding an antenna;

introducing the carrier foil and the antenna into the recess of the metal layer;

forming at least a part of a body of the data carrier by arranging the metal layer between a first plastic layer and a second plastic layer, each of the first plastic layer and the second plastic layer being attached to the metal layer.

19. The method according to claim 18, wherein introducing the carrier foil into the recess includes attaching the carrier foil to the first plastic layer at a position where the recess of the metal layer is to be positioned.

20. The method according to claim 18, wherein introducing the carrier foil into the recess includes inserting the carrier foil into the recess.
