Abstract

An electronic circuit for an electronic memory card that is capable, without electrical contact, of exchanging information with a reader device. The electronic circuit includes a coupling antenna for communicating with the reader device, and a semiconductor die connected to the antenna. On a support sheet made of plastics material are mounted a coupling antenna provided with two electrical connection terminals; and attached to the electrical connection terminals, a semiconductor die having protruding contacts. A whole intermediate sheet, i.e. one without an opening formed therein, covers the semiconductor die and the support sheet. An outer sheet is placed on the intermediate sheet. The sheets and the semiconductor die are laminated to form a contactless card under heat and pressure such that the semiconductor die becomes embedded into the intermediate sheet.
