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.

Abstract: A composite film material usable in a data carrier card body includes a first outer plastic layer, an inner plastic layer and a second outer plastic layer, all the layers together forming a co-extruded composite. The plastic material of the first outer layer is a polyethylene terephthalate glycol copolymer (PETG) or contains a PETG, the plastic material of the inner layer is a thermoplastic copolyester elastomer (TPC) or contains a TPC, and the plastic material of the second outer layer is a PETG or contains a PETG.

Abstract: The invention is directed to a method for manufacturing a foil having a variable strip geometry, which makes it possible to supply a foil that bears a complex security feature. The present invention is further directed to a corresponding data carrier having the foil supplied, and to the foil itself. The invention further relates to an extruder system for manufacturing a foil having a variable strip geometry and to a computer program product having control commands that implement the proposed method and/or operate the proposed extruder system.

Abstract: A portable data carrier is composed of several foils, wherein the data carrier has a three-dimensional high embossing on at least one of its outsides. At least one foil containing at least one additive is arranged in the region of the high embossing. The additive has a dichroic property such that the additive reflects a different color in dependence on the viewing angle.

Abstract: A foil composite material usable as a layer in a card body of a portable data carrier, that includes one outer plastic layer, one inner plastic layer and one second outer plastic layer. All the layers jointly form a coextruded composite, and the plastic of one outer layer is a thermoplastic polymer or a mixture thereof. The plastic of the one inner layer is a mixture of at least one thermoplastic elastomer and at least one thermoplastic polymer. The plastic of the second outer layer is a thermoplastic polymer or a mixture thereof.

Abstract: A data carrier card, in particular a chip and/or magnetic strip card, has a card body comprising one or more films and a security thread integrated in the card body. The security thread, or at least a substrate of the security thread, is coextruded in the form of a thread strip in one of the films.

Abstract: A card body for a portable data carrier, in particular a chip card or magnetic strip card, and a method for manufacturing a card body. The card body includes at least a coextruded foil having at least two areas with different material properties. By using coextruded foils a card body consisting of a plurality of alternating opaque and transmissive strips as well as a card body with a window can be formed in a simple fashion.

Abstract: A sheet document is based on a one-pieced, coextruded composite strip layer having a thickness of 10 to 110 ?m defining over its area at least two different materials that are configured side by side as strips. At least one of the strips is transparent or translucent and at least one strip opaque. On the composite strip layer there is applied an ink-receiving layer and/or a printed pattern that has a recess that at least partly is configured above a transparent/translucent strip and together with the non-covered region of the transparent/translucent strip forms a window.

Abstract: A data carrier card and a method for producing a data carrier card, in particular a chip card or magnetic stripe card. The data carrier card has a card body having one or several foils, where the foil or at least one of the foils is a coextruded foil having at least two areas with different material properties. The use of coextruded foils makes it possible to form in a simple manner different areas in the card body which differ from each other in material quality. In particular, it is possible to form for example a data carrier card with a card body having a plurality of alternating opaque and transmissive strips or with window strips and/or windows enclosed in the surface of the card body.
