Abstract
The invention relates to a flat transponder having an electronic circuit which is arranged in a layer or in a layer composite and which contains at least one chip and conductor tracks or conductor wires, and also to a method for the production thereof. The invention is based on the object of specifying a transponder of the type mentioned at the beginning and a method for the production thereof which is flexible, has the most uniform thickness possible and can be bonded to further elements by means of water-based adhesives, its electronic components largely being protected against damage by bending and against being detected by feel. According to the invention, the object is achieved by a transponder in which the circuit is arranged in or on a circuit carrier (7) made of plastic, on whose two larger opposite outer surfaces a paper layer (6) applied by lamination is in each case applied.
