Zusammenfassung:A method is provided for producing a chip card body having a metallic core layer for a contactless or dual-interface chip card. A slot in the metallic core layer for reducing eddy currents is generated not in the metallic multiple-copy sheet itself but instead only in the metallic core layer extracted from the metallic multiple-copy sheet. In this way, there are no short-circuit-forming metal chips left in the slot, since the slot is generated only after the extraction of the metallic core layer from the multiple-copy sheet.
