In the interconnection process of public transport IC card, the particularity of transaction data consist in reformed terminals, IC cards and background system. Combining with the demand of combined stress test, the highefficiency and controllable parameters system is presented in this paper, in which the platform terminal, IC card, both the stress and the performance of software and hardware for the system can be test. Meanwhile, the test function of the system can expand to other test projects such as error rate of read and write for the terminals, distances of read and write for the IC card, flash memory and trading time. The effect of the actual operation shows that, in the process of interconnection of bus IC card, the system conforms to test requirements such as stress test and so on.
