Producing a card with a transponder comprising a chip connected to a single-layer metal wire coil embedded in a thermoplastic material (TPM) comprises placing the coil on the TPM, passing current through the coil so that the TPM is locally softened and the coil sinks into the TPM, laminating or gluing a covering layer onto one side of the TMP and releasably attaching a support layer to the other side with an adhesive.
