Research On And Realization Of The Contactless Smart IC Card Toll System In Public Transportation Based On The Mixture Model Of C/S And B/S

With the development of China' s Golden Card Project, IC card has found wide applications in banking, public transportation, gas industry, and power supply, etc, of which the application of the Contactless Smart IC card , functioning as the e-currency , to the city public transportation system is the best choice nowadays. The system is large-scale in construction and highly demanding to reliability and safety. Moreover, it brings great economic results to and exerts dramatic social influence on public transportation system and city construction.With a view to the development of practical projects, the paper systematically deals with the design and realization of the Contactless Smart IC card toll system in city public transportation. It begins with introductions to the management information system, the development of the Contactless Smart IC card at home and abroad, as well as the resources of the subject, followed by the general introduction to the functional design of system and its structure. Finally, it illustrates in detail the solutions to and the realization of the system safety. The paper mainly focus on these two aspects to solve the safety problems of the system, identity recognition and the formation, distribution and delivery of the key code.The system is characterized by adopting the mixture model of C/S and B/S and using the key code as identity recognition. Its design tallies with regular technical requirements of the multi-functional card made by the National Construction Department, a good start for the further development of the city multi-functional card.
