PASSIVE SMART CARDS, METAL CARDS, PAYMENT OBJECTS AND SMART JEWELRY |
摘要 |
RFID devices comprising (i) a transponder chip module (TCM, 1410) having an RFIC chip (IC) and a module antenna (MA), and (ii) a coupling frame (CF) having an electrical discontinuity comprising a slit (S) or non-conductive stripe (NCS). The coupling frame may be disposed closely adjacent the transponder chip module so that the slit overlaps the module antenna. The RFID device may be a payment object such as a jewelry item having a metal component modified with a slit (S) to function as a coupling frame. The coupling frame may be moved (such as rotated) to position the slit to selectively overlap the module antennas (MA) of one or more transponder chip modules (TCM-1, TCM-2) disposed in the payment object, thereby selectively enhancing (including enabling) contactless communication between a given transponder chip module in the payment object and another RFID device such as an external contactless reader. The coupling frame may be tubular. A card body construction for a metal smart card is disclosed. |

1. An RFID device comprising:
a transponder chip module (TCM) comprising an RFID chip (IC) and a module antenna (MA); characterized by: a coupling frame (CF) comprising a conductive surface and having an electrical discontinuity comprising a slit (S) or non-conductive stripe (NCS) extending through the surface from an outer edge thereof to an inner position thereof, wherein the coupling frame is disposed so that the slit overlaps a portion of the module antenna. |
