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.
Claims19
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.
