The invention relates to a datasheet (1) for integrating into a preferably book-like security and/or value document. The datasheet (1) is made of at least two stacked layers (2, 3) made of an organic polymer material. A textile (5) is arranged at least in a sub-region between the layers (2, 3) and outside of the layers (2, 3) so as to form a tab (4), and the textile (5) is at least partly coated on one or both sides and/or saturated with an organic binder (6) at least in the region between the layers (2, 3) and is bonded to the two layers (2, 3) by means of the binder (6).

A multiple ply printed product and a method of producing it are described. The method comprises providing a substrate layer having a first surface supporting at least one wireless communication chip and a second surface, reverse to the first surface. A first paper stock having a first surface and a second surface is also provided. A first bonding operation is performed to substantially bond together the first surface of the substrate layer and the second surface of the first paper stock, to sandwich the wireless communication chip between the first paper stock and the substrate layer; providing a second paper stock having a first surface and a second surface. At least one of the first surface of the first paper stock and the second surface of the second paper stock may be printed on. A second bonding operation is performed to bond together the first surface of the second paper stock and the second surface of the substrate layer, to form a multiple ply printed product where the first surface of the substrate layer supports a plurality of wireless communication chips and the multiple ply printed product is a sheet on which is printed a plurality of business cards, each business card corresponding to a respective wireless communication chip.

A multilayer body with a carrier and a layer arranged thereon which comprises electrically conductive material in such an arrangement comprises an information area and a background area (18) which are galvanically separated from each other. In each information area a first zone (10) with electrically conductive material is provided, over the entirety of which electrically conductive material is conductively connected to it. In each background area a plurality of second zones with electrically conductive material is provided, which are galvanically separated from each other. Each first zone (10) preferably occupies a surface area that is at least five times larger than each of the second zones. The electrically conductive material is preferably provided with an average surface coverage which varies over all information areas and background areas (18) by less than 25%. A homogeneous appearance of the multilayer body is thereby ensured, and an item of information provided in the information area, provided by the shape, size and/or alignment of the first zone, is not visible without aids, and therefore cannot be copied.

A system and method for using a payment device having identifying numbers configured in aligned segments in order to facilitate use of the payment device. A mobile device generates a Web page, the Web page having four vertically stacked windows, each for receiving first, second, third, and fourth segments of a payment account number, respectively. The mobile device receives entry of the first, second, third, and fourth segments of the payment account number into the four vertically stacked windows, respectively. The mobile device transmits the payment account number to a Web site, wherein the Web site performs a payment transaction using the payment account number.

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.
