The Design And Implementation Of Financial IC Card System Based On SOA Architecture

At present, due to magnetic stripe card’s technical characteristic,it determines its information is easy to read and forged. The financialIC card system makes up the defect of the magnetic stripe card in technology.A set of advanced, safe and applicable financial IC card system urgentlyneeds to be established.Paper first expounded the developing background and present situationof the financial IC card, and analyzed the SOA principles and technical.Through analyzing the key technology, it described the Web Services overalltechnical architecture and its principles of design in use. The systemsused the spiral model in software engineering for development, includingsystem requirements analysis, system design and implementation and systemtesting, etc. In the requirements analysis, it used the analysis methodof the business model and analyzed the functional and non-functionalrequirements of the system. System was realized through top-down mannerfrom function to the underlying system. Overall architecture consisted ofcard issuers business systems, card issuers key management center and cardpersonalization. Finally, according to the situation of the operation ofthe system, we designed the test cases, analyzed the questions and improvedit.Adoption of SOA architecture reduced the coupling of the system andimproved the security of financial IC card. It meets the demand of customersand provided a reference for the development of the IC card system in thefuture.
