Token with an electronic chip and methods for manufacturing the same

A method of making a device comprising a flat body made of a thermosetting plastic material, the flat body comprising at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces, the cavity being adapted to receive an electronic identification device, at least one plug made of a thermosetting plastic material, the at least one plug being adapted to be inserted into the cavity, wherein the electronic identification is retained in the flat body when the at least one plug is inserted into the cavity, the method comprising:

• making the flat body;
• forming the cavity in the flat body;
• placing the electronic identification device in the cavity;
• inserting the at least one plug in the cavity;
• and
• fixing the at least one plug to the flat body.

A method of making a device comprising a flat body made of a plastic material, the flat body comprising at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces, the cavity being adapted to receive an electronic identification device, at least one plug made of a plastic material, the at least one plug being adapted to be inserted into the cavity, wherein the electronic identification is retained in the flat body when the at least one plug is inserted into the cavity, the method comprising:

• making a preform body;
• forming the cavity in the preform body;
• placing the electronic identification device in the cavity;
• inserting the at least one plug in the cavity, the at least one plug, the electronic identification device, and the preform body comprising a subassembly;
• inserting the subassembly in a thermocompression mold;
• and
• fixing the at least one plug to the preform body using the mold so as to retain the electronic identification device within the preform body,
• wherein the fixing forms the flat body.

A device comprising:

• a flat body made of a plastic material, the flat body comprising at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces;
• an electronic identification device arranged in the cavity;
• at least one plug made of a plastic material, the at least one plug being adapted to be inserted into the cavity,
• wherein the electronic identification device is completely enclosed and retained in the flat body when the electronic identification device is inserted into the cavity and when at least one of:
• the at least one plug is deformed after being inserted into the cavity;
• and
• the flat body is deformed after the at least one plug is inserted into the cavity.

A device comprising:

• a flat preform body made of a thermosetting plastic material, the flat preform body comprising at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces;
• an electronic identification device arranged in the cavity;
• at least one plug made of a thermosetting plastic material, the at least one plug being adapted to be inserted into the cavity,
• wherein the electronic identification device is retained in the flat body when the electronic identification device is inserted into the cavity.
