Data carrier having separately provided integrated circuit and induction coil

DETAILED DESCRIPTION I claim: 1.
A data carrier having a body comprising: at least one layer; an integrated circuit; and at least one coil having leads integrally formed with the coil and forming part of the body; characterized in that: a module bearing the integrated circuit and at least two contact elements is electrically connected via said contact elements with the leads of the coil; the module and the layer of the body are provided separately; the module further comprises outer contact surfaces; the body has a two-step recess for receiving the module, the two-step recess having a first step and a second step which is deeper than the first step; and the coil is disposed on the first step.
2.
The data carrier of claim 1, characterized in that the at least one layer of the body comprises a cover layer.
3.
The data carrier of claim 1, characterized in that the at least one layer of the body comprises an insulating layer and in that the coil is formed as a flat coil which is glued to the insulating layer of the body as a finished wire-wrapped coil.
4.
The data carrier of claim 1, characterized in that the coil extends essentially over an entire surface of the body.
5.
The data carrier of claim 1, characterized in that the leads of the coil and the contact elements of the module are disposed opposite each other within a plane of the body.
6.
The data carrier of claim 5, characterized in that the leads of the coil are glued electroconductively to the contact elements of the module.
7.
The data carrier of claim 1, characterized in that the at least one layer of the body comprises an inner layer of the body.
8.
The data carrier of claim 1, characterized in that the at least one layer of the body comprises an injection molded body part.
9.
The data carrier of claim 1, characterized in that the at least one layer of the body comprises an insulating layer of the body and in that the coil is printed on the insulating layer of the body as an electroconductive layer.
10.
The data carrier of claim 1, characterized in that the coil is stamped in a layer of the at least one layer of the body by a hot stamping method
