Patent ID: 8727215

Claim:
A test device for a magnetic stripe decoder chip, wherein the magnetic stripe decoder chip comprises at least one track signal receiving end, the test device comprising: a signal generator, sequentially outputting a plurality of test waveform signals, wherein the test waveform signals are formed by amplifying or reducing a period of a basic track signal generated by a control unit in different magnifications; a chip slot physically receiving the magnetic stripe decoder chip; a signal conversion circuit, connected electrically between the signal generator and the chip slot, wherein the signal conversion circuit comprises at least one transformer, a primary side of the at least one transformer is connected electrically to the signal generator, a secondary side of the at least one transformer is connected electrically to the chip slot, at least one transformer converts the test waveform signals into a plurality of false track signals and outputs the false track signals to one of the at least one track signal receiving end of the magnetic stripe decoder chip; and the control unit, connected electrically to the chip slot, receiving at least one decoding string generated respectively by decoding the false track signals through the magnetic stripe decoder chip, and comparing the at least one decoding string with a test string represented by the basic track signal, the comparing thereby testing the decoding and operational parameters of the magnetic stripe decoder chip without relative motion between a magnetic stripe card and corresponding reader.
