Abstract:
A dual range proximity and in-range smart card data transaction system, comprising:a triggering station comprising a triggering transceiver for effecting data transfer with a smart card by inductive coupling communication when in a predetermined range thereof;a send and receive station for effecting bi-directional communication with the smart card by inductive coupling when in proximity therewith;the smart card comprising:a semiconductor device coupled to a coil antenna for effecting data communication with a remote coil antenna so as to receive a signal therefrom, andan amplifier coupled to the coil antenna for amplifying said signal so as thereby to extend an operating range of the smart card and allow an in range communication with the triggering station,a battery for supplying energy to the amplifier and to components of the smart card during in-range mode,a card triggering receiver for effecting inductive coupling and defined area of communication with the triggering station so as to receive data therefrom upon passage within a predetermined area of the triggering station,a memory for storing a predetermined instruction set for process monitoring,a processor coupled to the card triggering receiver and to the memory and responsive to the predetermined instruction set for operating functions of the smart card, anda card transceiver coupled to the processor for effecting non-contact inductive coupling communication with the send and receive station and being at least partially powered by energy received therefrom for allowing data transfer when within close proximity of the send and receive station;whereby the send and receive station may load predetermined instruction sets into and retrieve data from the smart card for processing by the processor and for data transfer of processed data to the send and receive station via the card transceiver and for receiving data via the send and receive station.
