Abstract
A method for manufacturing a card body for a chip card, includes the steps of: supplying a metallic base body with two opposite main faces and a circumferential peripheral face connecting the two main faces, wherein in the base body a module opening for receiving a chip module has already been produced or will still be produced in a module opening zone, and producing a slot on the peripheral face between the two main faces. The slot is formed from the peripheral face up to the module opening or up to the module opening zone. An entry angle (α) of the slot into at least one of the two main faces is not equal to ninety degrees with respect to the main face.

A method for manufacturing a card body for a chip card with the steps of:
- supplying a metallic base body with two opposite main faces and a circumferential peripheral face connecting the two main faces,
- wherein in the base body a module opening for receiving a chip module has already been produced or will still be produced in a module opening zone, and
- producing a slot on the peripheral face between the two main faces,
- wherein the slot is formed from the peripheral face up to the module opening or up to the module opening zone, and
- wherein an entry angle of the slot into at least one of the two main faces is not equal to ninety degrees with respect to the main face,
- wherein at least a portion of the slot is formed in an arched shape from one main side to the other main side so that a first wall of the slot has a concave portion and an opposite second wall of the slot has a convex portion,
- wherein the convex portion engages in the concave portion.
A card body for a chip card, having:
- a metallic base body with two opposite main faces and a circumferential peripheral face connecting the two main faces,
- wherein in the base body a module opening for receiving a chip module has already been produced or will still be produced in a module opening zone, and
- a slot which extends from the peripheral face of the base body to the module opening or to the module opening zone and which extends between the two main faces,
- wherein an entry angle of the slot into at least one main face is not equal to 90° with respect to the main face,
- wherein a first wall of the slot has a concave portion and that an opposite second wall of the slot has a convex portion,
- wherein the convex portion engages in the concave portion.
