Title: DATA CARRIER WHICH CAN BE OPERATED WITHOUT CONTACT
Abstract:
The invention relates to a data carrier (1) having an integrated circuit (7) and at least one insulating carrier substrate (10), on which a transmission element (2) is fitted for transmitting data to an external device. The integrated circuit (7) is inserted into the data carrier (1) either directly, or packed in an electronic module (4). In order to produce an electric connection between the integrated circuit (7) or the electronic module (4) and the transmission element (2), the data carrier (1) has electrically conductive surfaces (3, 17) situated opposite the two main surfaces of the electronic module (4) or of the integrated circuit (7). The electrically conductive surfaces (3, 17) are each connected to the contact surfaces (5) of the electronic module (4) situated opposite them, or to the contacts (8) of the integrated circuit (7); they are also connected, in pairs, to the electrically conductive surfaces (3, 17) situated on the other side of the electroni module or of the integrated circuit (7). Each pair of electrically conductive surfaces (3, 17) is furthermore connected to the transmission element (2) in such a way as to be electroconductive. The transmission element (2) can be configured as a printed coil with broadened coil ends (3); each end constitutes one of the electrically conductive surfaces (3, 17) in the pair.
