Patent ID: 8172978

Claim:
A method for manufacturing a radio frequency identification device (RFID), said device featuring an antenna and a chip connected to the antenna, said method including the following steps: printing an antenna having contacts on an antenna support made of paper or synthetic paper, placing adhesive dielectric material between said contacts of the antenna, positioning an integrated circuit module on said antenna support, said module comprising groups of contacts and a chip connected to groups of contacts inside an encapsulation of the module, so that the groups of contacts of said module are opposite said contacts of said antenna, placing on said antenna support a thermoplastic layer and a paper or synthetic paper layer, the thermoplastic layer and the paper or synthetic paper layer each being provided with a recess at the location of the module, laminating together the antenna support, the thermoplastic layer and the paper or synthetic paper layer in order to electrically connect said module to said antenna, such that the antenna support layer and the paper or synthetic paper layer pinch the module at the location of groups of contacts and contacts of the antenna, with the pinch being maintained by the thermoplastic layer which, after the lamination step, has hardened.
