摘要:
A security element for a document of value is arranged on a transparent layer such as a film and includes a first periodic, optical structure, for example a grid of lines or a grid of points, which forms a first coating on a first side of the transparent layer, and a second periodic, optical structure, for example a grid of lines or a grid of points, which forms a second coating on the second side, which is disposed opposite the first side of the transparent layer. The first optical structure and the second optical structure overlap such that, as viewed by outside observer at a certain, predetermined viewing angle (α) or lighting angle, the structures show a color-changing effect.

A method is proposed for providing position data for a chip card having portions for receiving or detecting position data of a localisation unit by the localisation unit, wherein the localisation unit is spatially separate from the chip card; transmitting the position data from the localisation unit to the chip card via a contactless interface with use of a cryptographic protocol; executing a distance-bounding protocol between the chip card and the localisation unit, wherein the distance-bounding protocol then concludes successfully precisely when the spatial distance between the chip card and localisation unit does not exceed a predefined maximum distance; and executing a chip card function with successful conclusion of the distance-bounding protocol, wherein the chip card function uses the transmitted position data as position data specifying the current position of the chip card.

The invention relates to a security element (2), in particular in the form of a multi-layer flexible film body, with a top side facing an observer and a back side facing away from the observer, as well as a method for the production thereof. The security element (2) has one or more light-emitting elements arranged in a first area (30) of the security element which radiate light when activated and in particular are formed in each case of a self-luminous, electrically operated, display element. The security element (2) has, in the first area (30), one or more transmissive diffraction structures. The one or more transmissive diffraction structures are arranged such that at least a part of the light radiated by the activated one or more light-emitting elements transmits through at least one partial area of the transmissive diffraction structures.

This present invention serves to simplify manufacture of a contactless data transmission device (50). This device (50) has an electrically insulating carrier (1), a circuit element arranged on the carrier (1) made from a continuous antenna conductor track (2) in the form of at least one spiral winding (4, 5, 6) and respectively one terminal contact (15, 16) at the ends thereof as well as an electronic component (3) with at least two contact points (11, 12) electrically connected with the circuit element. The electronic component (3) is placed in a mounting region (10) above the at least one spiral winding (4, 5, 6). The at least two contact points (11, 12) of the component (3) are electrically connected with a respective terminal contact (15, 16) of the antenna conductor track (2). At least one spiral winding (4, 5, 6) is branched outside the mounting region (10) between two respective branching points (7′, 7″; 8′, 8″; 9′, 9″) into at least two spiral winding branches (4′, 4″; 5′, 5″; 6′, 6″). The data transmission device (50) is a component part of a valuable and/or security document (100).
