摘要:
A chip card configured as a metal card is RFID-capable on both sides, by the windings of the transponder coil being formed by the metal layer itself. Gaps between the windings of the transponder coil are filled with insulating material. A chip module is arranged above the ends of the transponder coil such that these ends are not visible for the viewer.
