Abstract
The invention concerns a method for manufacturing a radio frequency identification device (RFID), featuring a flat and flexible substrate made of polycarbonate equipped with an antenna (14) composed of conductive ink fully encased in the polycarbonate and a chip or integrated circuit module (29) connected to the antenna, the antenna formed by the winding of several turns features a turn overlap zone, an insulating strip of dielectric material separating the turns of the antenna in the overlap zone, the edges of the device being completely uniform so that no lines of demarcation between the various layers are visible, thereby preventing all attempt of delamination of the device over its thickness.
