摘要 A chip card with a chip module having an integrated circuit and, for external contacting, has on a main face a contact zone with a number of contact areas which are spaced apart from one another and are electrically connected to the integrated circuit. At least one contact area is made up of first functional regions with first surfaces and of second functional regions with second surfaces, and the first surfaces of the first functional regions lie higher with respect to the main face than the second surfaces of the second functional regions.
