Simulating Technique of IC Card Online Transaction

In order to resolve the problems of Computer network system Online transaction in IC card application product's developing and testing, Simulating the system is necessary. A successful simulation is not only to solve many problems, but also to provide a visual and convenient condition for exchange and training, thereby imploring effect of developing work. The paper takes a typical online transaction, such as Credit For Load to describe the Simulation system's Composing, key algorithm and main method of program design.
