Patent ID: 11250305

Abstract:
An RFID enabled metal transaction card comprising (i) a transponder chip module (TCM) having a RF payment chip (IC) and a module antenna (MA), (ii) a coupling frame (CF) in the form of a metal card body (MCB) having an electrical discontinuity comprising a slit (S, SCF) and (iii) a discontinuous metal frame (DMF) assembled to the metal card body (MCB) in a peripheral area thereof and having a slit (S, SDMF). The discontinuous metal frame (DMF) is electrically isolated from the metal card body (MCB) and may be coated with an insulating medium. The DMF camouflages the slit in the metal card body and mechanically stabilizes the structure of the card body, especially during insertion in an automatic teller machine (ATM) or point of sale (POS) terminal.
