Portable data carrier and method for the production of the data carrier

1. A portable data carrier, comprising:

a card body having at least one surface;

a chip module having an antenna for near-field communication which is incorporated in the card body;

a base gloss varnish layer applied on the at least one surface of the card body;

a printing ink layer on the at least one surface of the card body;

a gloss varnish layer on the printing ink layer;

a plastic layer on the gloss varnish layer, the plastic layer being transparent and having a layer thickness greater than 0.5 mm; and

a through bore in the data carrier at a place outside the area of the antenna or the chip module, said through bore being employable for carrying the data carrier.

2. The portable data carrier according to claim 1 , wherein the printing ink layer is provided on the card body on one side or on both sides.

3. The portable data carrier according to claim 1 , wherein the printing ink layer is an offset printed layer or a screen printed layer.

4. The portable data carrier according to claim 1 , wherein the card body:

is multilayer,

the material of the card body is white or colored, and

the material comprises PVC, PET or ABS.

5. The portable data carrier according to claim 1 , wherein the plastic layer is an epoxy resin.

6. The portable data carrier according to claim 1 , wherein the base gloss varnish layer and the gloss varnish layer are configured to prevent delamination by having very good adhesive forces between the printing ink layer and the card body.

7. A method for producing a portable data carrier, wherein the data carrier comprises a card body with an incorporated antenna and a chip module for near-field communication, comprising the steps:

coating a surface of the card body with a gloss varnish-like base gloss varnish;

coating the surface of the card body with a printing ink;

coating the printing ink with a gloss varnish layer;

laminating the card body with the printing ink layer and the gloss varnish layer;

coating the gloss varnish layer with a plastic layer, wherein the plastic layer is thicker than 0.5 mm; and

heating the portable data carrier to cure the plastic layer, wherein the plastic layer is transparent after curing.

8. The method according to claim 7 , wherein the card body is a multilayer PVC material and said PVC material becomes monolithic under the action of heat during the heating steps.

9. The method according to claim 7 , wherein a hole is provided in the data carrier at a place outside the area of the antenna or the chip module.

10. The method according to claim 7 , wherein the data carrier is fixed by means of spot welding before lamination.

11. The method according to claim 7 , wherein the base gloss varnish layer and the gloss varnish layer are configured to prevent delamination by having very good adhesive forces between the printing ink layer and the card body.

12. A method for producing a multiplicity of portable data carriers according to the method of claim 7 , wherein the individual card bodies are all manufactured from a single workpiece and are singled by means of punching only after lamination.

13. The method according to claim 12 , wherein the final shape of the data carrier is achieved by means of fine blanking after singling.
