Abstract
In a method for manufacturing a multi-layered card body with a metallic core layer and at least one cover layer for a contactless or dual-interface chip card an adhesive is applied to at least one side of the metallic core layer in such a manner that a slot in the metallic core layer is filled with the adhesive. The metallic core layer is subsequently laminated with the cover layer by means of the adhesive. As a result, no short-circuit can occur in the slot, e.g. by metal chips remaining in the slot, because the slot has already been filled with the adhesive.
