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.

A method for producing a card body for a chip card, comprising 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.
The method for producing a chip card having a card body and a chip module embedded at least partly in the card body, comprising 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;
- incorporating a cavity having a bottom area for receiving the 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;
- transferring the excess material into the slit;
- and
- inserting the chip module into the cavity.
A card body for a chip card having a metallic core which is covered at least partly with a plastic layer at least on a main area and which has a slit running from an outer edge of the main area into this main area, and having a cavity in the plastic layer which covers the slit at least partly,
- wherein the cavity has a bottom area with an excess material, with respect to the bottom area, arranged at least along the slit.
