Abstract

A method for changing a geometry of an edge of a portable data carrier, wherein the geometry of the edge is changed in order to work on the edge and the outer side of the data carrier proceeding from a common side, without a spatial location of the data carrier being changed.

First claim

The invention claimed is:

1. A method for changing a geometry of an edge of a portable data carrier, the method comprising:
changing the geometry of the edge of the portable data carrier by removing material of the edge, the changed edge comprising at least four edge segments defining a perimeter of an outer side of the data carrier; and
marking the changed edge and the outer side of the data carrier without a spatial location of the data carrier being changed;
wherein the geometry of the edge is changed in order to mark the edge and the outer side of the data carrier proceeding from a common side, without the spatial location of the data carrier being changed;
wherein the portable data carrier comprises at least two foil layers, the changed geometry of the edge extending through each of the at least two foil layers;
wherein the changed edge and the outer side of the data carrier are marked in the same marking operation; and
wherein a geometric form of at least one of the at least four edge segments varies relative to a geometric form of another of the at least four edge segments.

2. The method according to claim 1 , wherein the edge is marked by printing the edge by means of a printing method.

3. The method according to claim 1 , wherein the edge is marked by marking the edge by means of a laser method.

4. The method according to claim 1 , wherein the geometry of the edge is changed such that it is diagonal and/or circular with regard to the outer side of the data carrier.

5. The method according to claim 1 , wherein a data carrier is employed which has in its interior at least one white foil and an overlay foil as an outermost foil.

6. The method according to claim 1 , wherein the changed geometry of the edge extends through a total height of the data carrier.

7. The method according to claim 1 , wherein the changed geometry of the edge extends through only a part of a total height of the data carrier.

8. The method according to claim 1 , wherein the changed geometry of the edge includes a bevel formed on the outer side of the data carrier and an opposing side.

9. The method according to claim 1 , wherein the changed geometry of the edge includes a rounded form.

10. The method according to claim 1 , wherein the geometric form passes from a circular form to a beveled form.

11. The method according to claim 1 , wherein the changed geometry of the edge includes a rounded form and a beveled form.

12. The method according to claim 1 , wherein the geometric form of the at least one of the four edge segments varies relative to a geometric form of another of the four edge segments prior to the marking of the changed edge.

13. The method according to claim 1 , wherein the geometric form of at least two of the four edge segments varies relative to a geometric form of another of the four edge segments.

14. The method according to claim 1 , wherein the geometric form of each of the four edge segments varies relative to a geometric form of each of the other edge segments.

15. The method according to claim 1 , wherein the changed edge comprises at least six edge segments defining the perimeter of the outer side of the data carrier.

16. A method for changing a geometry of an edge of a portable data carrier, the method comprising:
changing the geometry of the edge of the portable data carrier by removing material of the edge, the changed edge comprising four edge segments defining a perimeter of an outer side of the data carrier; and
marking both the changed edge and the outer side of the data carrier from a common side without a spatial location of the data carrier being changed;
wherein the portable data carrier comprises at least two foil layers, the changed geometry of the edge extending through each of the at least two foil layers;
wherein the changed edge and the outer side of the data carrier are marked in the same printing operation; and
wherein a geometric form of at least one of the four edge segments varies along the outer side of the data carrier.

17. The method according to claim 16 , wherein the geometric form of at least two of the four edge segments varies along the outer side of the data carrier.

18. The method according to claim 16 , wherein the geometric form of each of the four edge segments varies along the outer side of the data carrier.

19. A method for changing a geometry of an edge of a portable data carrier, the method comprising:
changing the geometry of the edge of the portable data carrier by removing material of the edge; and
marking the changed edge and an outer side of the data carrier without a spatial location of the data carrier being changed;
wherein the geometry of the edge is changed in order to mark the edge and the outer side of the data carrier proceeding from a common side, without the spatial location of the data carrier being changed;
wherein the portable data carrier comprises at least two foil layers, the changed geometry of the edge extending through each of the at least two foil layers;
wherein the changed edge and the outer side of the data carrier are marked in the same marking operation; and
wherein the changed edge has a geometric form which varies along the outer side of the data carrier and passes from a circular form to a beveled form.
