Abstract
A method for producing a card body for a chip card, includes the steps of: providing a flat card body having a metallic core, wherein the metallic core is covered at least partly with a plastic layer at least on a main area and wherein the metallic core has a slit running from an outer edge of the main area into this main area; and incorporating a cavity having a bottom area for receiving a chip module into the plastic layer in such a way that the cavity covers the slit at least partly and that at least along the slit an excess material remains with respect to the bottom area.
