Smartcard comprising:
- a transponder chip module (TCM) comprising an RFID chip (IC) and a module antenna (MA) having two ends connected with two terminals of the RFID chip (IC);
- and
- a card body (CB) comprising multiple layers, wherein:
- a first layer of the card body comprises a first coupling frame (CF-1) having a first opening (MO-1) surrounding a top, a left and a bottom edges of the transponder chip module (TCM);
- and
- a second layer of the card body comprises a second coupling frame (CF-1) having a second opening (MO-2) surrounding the top, a right and the bottom edges transponder chip module (TCM).
