    摘要： An RFID-type system is described in which a portable card receives a signal from a transceiver and outputs a phase modulated or amplitude modulated signal from which the transceiver derives information transmitted from the card. Alternatively, the card may have a coil with a self inductance of 3mH or more which, by altering the characteristics ofthe coil or a circuit connected thereto (loading the coil) facilitates a loading of the signal from the transceiver, which load change may be used for extracting the additional information.

    摘要： A device for and a method of outputting a magnetic field which is selected according to the type of card reader into which the device is inserted. Different card readers have different reader head types and different number of reader heads, and different modes of outputting the magnetic field, usually with the same information contents, are selected in order to cater for different reader types. In one example, the sensing coils of different reader heads may have different angles to the swipe plane, so that different field line angles may be selected to adapt to the actual reader head.

    摘要： An assembly of a card and a card reader, the card reader comprising a reading head configured to be positioned over a predetermined curve of the card while sensing the electromagnetic field and to output a signal relating to the field sensed, the card comprising an oblong field generator comprising at least two end portions configured to output at least part of the electromagnetic field, wherein the end portions are at least 1.8mm wide and positioned so that, when projected on to a plane of the surface, an edge of each end portion is positioned no more than 0.5mm from the curve and/or the curve not overlap the end portions in the projection. The curve is defined by the path of the reading head over the card. The card has a generator displaced in relation to standard cards where the generator is positioned directly under the curve.
