Abstract
A method for producing a security layered construction as well as a security layered construction for an identification document (61), particularly for personal identification, having a transponder layer (20) and at least one cover layer (38, 39), the transponder layer being covered using the at least one cover layer to form a seal with the wire conductor positioned interposed, and at least one viewing side (62) of the at least one cover layer or transponder layer being provided with security printing (63.
Claims33
A security layered construction comprising:
- a transponder layer, the transponder layer having a chip arrangement arranged on a transponder substrate and a wire conductor positioned in one plane on the transponder substrate to implement at least one coil turn, the wire conductor being in contact with terminal areas of the chip arrangement in order to form a transponder unit, the transponder substrate being made of a thermoplastic and being received between a first cover layer positioned opposite a chip housing of the chip arrangement and a second cover layer, and the transponder layer being covered using the first cover layer and the second cover layer to form a seal, a viewing side of the first or second cover layer or a viewing side of a binding cover layer arranged on each of the cover layers being provided with security printing having person-specific identifying data, the cover layers being made of a foamed plastic and the first cover layer has a window opening to at least partially receive the chip housing, the window opening being filled up with a partial region of the transponder substrate overlapping the chip housing in such a way that the partial region is flush with a top of the first cover layer.
