Patent ID: 8496183

Claim:
A non-contact IC card communication controller capable of selectively enabling or disabling reading of information recorded on a non-contact IC card that has a thickness of 0.8 mm or less and conforms to ISO 18092, the non-contact IC card communication controller comprising: a non-magnetic hollow metal frame having one cut-off portion sized 1-2 mm in width and 3-25 mm in length; and a non-magnetic metal piece positioned adjacent to the cut-off portion for repeatedly closing the cut-off portion so as to weaken and strengthen an eddy current that is generated in the non-magnetic hollow metal frame, wherein, the controller overlays the non-contact IC card such that the non-magnetic hollow metal frame and a coil antenna built in the non-contact IC card are overlapped so as to substantially conceal the coil antenna regardless of the cut-off portion being opened or closed, and wherein, when a magnetic field of a strength of 7.5 A/m is applied to read the information recorded on the non-contact IC card, the controller disables reading of information recorded on the non-contact IC card when the cut-off portion is closed by the non-magnetic metal piece, and the controller enables reading of information recorded on the non-contact IC card when the cut-off stays open.
