Abstract:
1. An arrangement comprising an object made at least partially of metal or precious metal comprising an electrically-conductive metallic surface having a top surface side and an RFID transponder for receiving energy from a reading device comprising a chip and an aerial structure, the chip and aerial structure are connected to one another and are directly embedded onto a substrate layer of the RFID transponder, wherein the substrate layer of the RFID transponder is directly integrated into the top surface side of the electrically-conductive metallic of the object made at least partially of metal or precious metal thereby enabling the RFID transponder to receive the energy from the reading device, wherein the RFID transponder is directly placed into a recess on the top surface side of the electrically-conductive metallic surface of the object and is disposed flush with the top surface side of the electrically-conductive metallic surface of the object made at least partially of metal or precious metal, wherein the substrate layer comprises a plurality of fixed, highly permeable ferromagnetic particles in a region of a spatial extension of the aerial structure of the RFID transponder on a top surface facing the electrically-conductive metallic surface, where the plurality of fixed, highly permeable ferromagnetic particles are oriented in such a way, that after being fixed-on a top surface of the substrate layer, the plurality of fixed, highly permeable ferromagnetic particles lie parallel to a magnetic field induced in the aerial structure of the RFID transponder and thereby suppress eddy currents, which occur when the RFID transponder is introduced into the magnetic field induced by a the corresponding reading device and wherein disposed between the highly permeable ferromagnetic particles are free spaces, which act as air gaps and wherein the substrate layer is a highly permeable material and wherein the object is an access card, a chip card or a card made of precious metal with RFID technology.
