A card-shaped data carrier includes an electronic chip module having at least one chip and a contact structure; and a card body having an arrangement region for receiving the chip module. The chip module is arranged in the arrangement region of the card body. The card-shaped data carrier has at least a first wood layer and at least a second wood layer. The card-shaped data carrier can be bent out of a rest position into a bent position by the application of an external force; at least one restoring element for increasing the restoring force of the card-shaped data carrier is arranged between the first wood layer and the second wood layer. The restoring element is designed such that the card-shaped data carrier can be automatically returned from the bent position to the rest position when the external force is no longer applied.

Card-shaped data carrier comprising wood

A method for producing a film for a card-shaped data carrier, includes the following steps: providing at least one first material in an extruder of an extrusion apparatus; heating the first material to form a melt; extruding the melt through a nozzle outlet gap of the extrusion apparatus; conveying the extruded melt on a roller arrangement that is adjacent to the nozzle outlet gap and includes at least one cooling roller; providing at least one transfer film; supplying the transfer film to the extruded melt on the cooling roller is so the security element contacts a surface of the extruded melt on the surface of the transfer film; transferring the security element from the surface of the transfer film onto the surface of the extruded melt; cooling the extruded melt comprising the security element to form the film.

A security feature for a data carrier, having a substrate, an encoded representation of the security feature arranged in or on the substrate, wherein a plurality of individual representations are contained in the encoded representation and wherein the plurality of individual representations are arranged in a division over a dimension of the security feature, and a decoder with a grid, wherein a grid pitch of the grid of the division corresponds to an integer multiple of the division or a halving of the division.

Security feature for a data medium, and data medium

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 varying of the geometry is effected by means of an adaptation of a melt flow of the extruder.

Coextrusion of periodically modulated structures

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. Varying of the geometry is effected by means of a movement of a position-variable distributor rail of the extruder.

A chip card configured as a metal card is RFID-capable on both sides, by the windings of the transponder coil being formed by the metal layer itself. Gaps between the windings of the transponder coil are filled with insulating material. A chip module is arranged above the ends of the transponder coil such that these ends are not visible for the viewer.

Chip card

A security document has a carrier element which has a surface with a principal plane and a personalization region. A personalization layer is applied to the surface, such that the surface of the carrier element in the personalization region is configured with a plurality of structure elements uniformly aligned with each other and raised with respect to the principal plane. The structure elements of the plurality of structure elements are configured immediately adjacent to each other and the structure elements are configured with a center distance between vertical axes of the respective structure elements of less than 250 &#x3bc;m.

Security document and method for producing a security document

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.

A multilayer, co-extruded foil stack has a layer of a layer having Tritan&#xae; and a layer arranged within the foil stack with a layer having polycarbonate. A card-shaped data carrier has at least the multilayer foil stack.

Multi-layer film stack and card-shaped data carrier

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.

Method for changing an edge of a portable card-shaped data carrier

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.

Coextruded foil composite material and its use in card bodies

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.

Portable data carrier comprising a relief structure

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.

Highly flexible foil composite material and its use in card bodies

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 elastomer (TPC) or containes a TPC, and the plastic material of the second outer layer is a PETG or contains a PETG.
