ABSTRACT:
The card comprises an insulating support (1) supporting a winding (4) which is used as an antenna, and an integrated circuit (9) electrically connected to the ends (7, 8) of the winding. According to the invention, the support (1) comprises on a structured surface (2) a cavity (3) on the walls and the bottom of which the tracks of the winding (4) are found which are formed further on the structured surface. The cavity (3) also includes the ends (7, 8) of the winding and contains the integrated circuit (9) which is pressed against the tracks. The cavity (3) is furthermore filled up with a polymerized protection resin (14) and a layer of insulating material (15) covers the structured surface (2) to which it is bonded.
