Abstract: A method for producing security patterns on an electronic module for a security document includes providing a dielectric film; producing through-holes in the dielectric film; depositing at least one metallic layer on upper and lower faces of the dielectric film leaving the through-holes open; engraving a set of functional metallic zones comprising a central zone forming an electrical ground and a set of electrical contacts separated from one another and separated from the electrical ground by non-metallized zones that expose the dielectric film, and a set of non-functional or decorative zones; and simultaneously engraving a first hollow security pattern by removing material in one of the functional metallic zones, and a second security pattern in relief relative to the dielectric film and obtained by removing material in a zone located outside the functional metallic zones forming the electrical contacts of the terminal block.

Abstract: An electronic module for a chip includes a first dielectric substrate provided on one of the faces thereof with a first microelectronic chip whose input/output terminals are connected to first connection pins which are arranged around the first microelectronic chip, and a second dielectric substrate which is placed directly opposite the first substrate and which is provided on one of the faces thereof with a second microelectronic chip whose input/output terminals are connected to second connection pins which are arranged around the second microelectronic chip. The first and second microelectronic chips are arranged on the faces of the substrates directed towards the interior of the electronic module. A dielectric shim has a calibrated thickness and separates the first and second dielectric substrates. The shim has through-holes or vacancies accommodating electrically conductive materials connecting some of the first connection pins to some of the second connection pins.

Abstract: An electronic module for a smart card has on a first face a terminal block of electrical contacts for contact with corresponding contacts of a card reader, and on a second face an antenna and a microelectronic chip within an encapsulation zone and provided with contact and contactless communication interfaces. The antenna has a plurality of turns at the periphery of the module and a proximal connection pad and a distal connection pad inside the encapsulation zone for connection to corresponding terminals of the contactless communication interface. The distal connection pad is located a short distance d from the edge of the encapsulation zone, and the internal edges of connection wells of the two contacts closest to the distal connection pad are spaced outward from the module relative to the internal edges of the connection wells of the other contacts.
