System and method for testing magnetic stripe decoding chip

摘要

A system and a method for testing a magnetic stripe decoding chip are provided. The system includes a host, a digital-to-analog converter, and a testing device. The host outputs simulation signal data. The digital-to-analog converter receives the simulation signal data and generates a test waveform signal representing a test string. The testing device includes a signal input terminal, a signal conversion circuit, a chip slot, and a processor. The terminal receives the test waveform signal. The chip slot is configured to receive a decoding chip. The circuit includes a transformer connected between the terminal and the chip slot, and is configured to couple the test waveform signal into a pseudo track signal. The processor receives a decoded string generated after decoding the pseudo track signal by the decoding chip. Through comparing the decoded string with the test string, a decoding function of the decoding chip can be determined.
