Abstract

A method for the manufacture of a contact-free card comprising a card body and an electronic module having an integrated circuit chip connected to an antenna, a frame is deposited on a lower thermoplastic sheet demarcating the edges of a cavity; the electronic module is positioned at the bottom of the cavity; this cavity is filled with a polymerizable resin; and the frame and the resin-filled cavity are covered with an upper thermoplastic sheet to which slight pressure is applied. The resin polymerizes, and the card is cut out within the frame.
