ABSTRACT:
An electronic module for data carriers having at least one integrated circuit includes an electrically conductive layer with contact surfaces for communication of the circuit with external devices and having an insulated layer which is connected to the conductive layer and has recesses for electrically connecting the contact surfaces with the circuit. Each recess protrudes partly into the contact surface adjacent the recess. The recesses may be formed in such a way that the area of insulating layer remaining in the center of the module takes up substantially only the integrated circuit surface.
