Abstract
Abstract The invention relates to a data carrier comprising a card body and an integrated circuit connected electroconductively via contact elements with at least one coil serving the purpose of power supply and/or data exchange of the integrated circuit with external devices. The invention is characterized in that the integrated circuit and the contact elements form a separate module known in the art and the coil is disposed on a card body constructed from one or more layers in known fashion. The coil is preferably formed as a flat coil.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
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.
Claim 2
Dependent Claim
115 words
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.
Claim 3
Dependent Claim
21 words
