Abstract: The invention relates to a card-shaped data carrier consisting of at least one layer (1, 2, 3). Visually readable information in the form of a changed optical characteristic is introduced into the layer. Said characteristic is changed by irreversibly changing the material by means of a laser beam. The absorption capacity of said layer (1, 2, 3) for at least one wavelength (?±?) is at least partially reduced due to the laser radiation.

Abstract: A description is given of a method for applying colored information to an object (4), the object having at least two different chromophoric particles, at least in a layer (4A) close to the surface, which change the color of this layer (4A) under the influence of laser radiation, laser radiation (1, 2, 3) having at least two different wavelengths (?1, ?2, ?3) being used in order to change the color of this layer (4A), the object (4) being acted on by laser radiation in the vector and/or raster method by means of a two-coordinate beam deflection device (6) and a focusing device (7) for focusing the laser radiation onto the layer (4A) of the object (4).

Abstract: The invention relates to a method for the recording of data, in particular, personal data on and/or in a data support, by means of electromagnetic radiation. A corresponding data support is made ready, on and/or in which a dye is at least locally provided and said dye is irradiated by means of said electromagnetic radiation of at least one wavelength range, such that a change in the color of the dye by bleaching occurs in the region of the irradiation. Said color change may be determined by machine and/or by the human eye. An improved counterfeiting and manipulation security for the data support is thus achieved.

Abstract: A conductor track supporting layer for laminating inside a chip card includes at least one conductor track and connecting areas that are connected to the conductor track. The conductor track is applied to the conductor track supporting layer during a screen printing method and is made of a screen printing paste. The conductor track supporting layer has indentations which are located in the area of the connecting areas and which are filled with the screen printing paste during the screen printing process. As a result, it is possible to produce conductor track supporting layers provided with connecting areas of varying thicknesses which enable the production of recesses in the chip cards, after the conductor track supporting layers are laminated in chip cards. These recesses expose the connecting i, areas for connection to electronic components. And, the sensitive strip conductors, also located in the chip card, are prevented from becoming damaged.

Abstract: Disclosed is a method for producing a chip card which is provided with a plastic card body (1) comprising several layers, an integrated circuit that is arranged in a chip module (2) and at least two additional electronic components (3,4) for producing an interactive chip card. The components and the chip module are connected to each other by means of strip conductors (4, 5, 9) which are arranged on a carrier layer (8) and metallic contact surfaces (7) which are connected to the conductors. According to the invention, several cover layers (10, 11) are mounted on the conductor carrier layer. Said cover layers are provided with recesses (15, 16, 15′, 16′) corresponding to the metallic contact surfaces (7).

Abstract: A method for manufacturing a chip card comprising a multi-layer plastic card body; an integrated circuit arranged within a chip module; at least one coil which serves for the energy supply and/or the data exchange between the integrated circuit with external devices, with the chip module having at least two metallic contacts for an electrically conducting connection of the integrated circuit with the terminals of the coil arranged on a coil carrier layer, comprising the steps of: providing the coil carrier layer with the coil and the coil terminals being arranged on same; providing a cover layer to be applied onto the coil carrier layer on the side of the coil terminals, with the cover layer comprising recesses which correspond to the coil terminals; providing at least one thickness compensation layer to be applied onto the cover layer; stacking of the card layers in registered relationship, with the cover layer being positioned in such a manner that each of the recesses in the cover layer comes to lie in the
