Design And Implementation Of Campus Card System Based On S50 Card

Promotion of information technology is the trend of social development. Colleges should seize the opportunities brought by the revolution of information technology, and make full use of smart card technology and network technology, so that the school system of The Armed Police Academy can become modernization and specialization. The "campus card" system is born for improving the scale and quality of The Armed Police Academy. The "campus card" system is an important part of the modern management. The "campus card" system integrates identification and comprehensive consumption into a unit, which is convenient to the teachers and students.This thesis aim at deploying the "campus card" project, and combining it with practical works, from the smart card system requirements to design and analysis and implementation of the "campus card" system to study how to design. By analyzing the relationship and characteristic between the functions of the smart card modules, and using the practical application of student card with school using times and the direction of using to analysis date systematically. Then according to the security problems which the students use the card to finding the reason, and through the management system to eliminate the hidden trouble of safety. A comprehensive analysis of the use of the card, the establishment of a set of all the function modules in the integrated management system, and through the "high cohesion, low coupling is tightly connected with the design idea of the" implementation of each module.The thesis firstly carries on the analysis of the demand of campus card system, the demand analysis, function module decomposition into system demand, and described one by one. Using the ongoing method of software engineering, the thesis define the summary of design of the system, and make the summary of design detail becoming detailed design. This thesis use the technology of.net of Microsoft in the encoded stage for integrating digital system of the school, like the educational system and so on. Finally, this thesis do complete functional test and overwhelming test for the accomplished system.Concretely, the “campus card” system making by the thesis, including card management center and consumption management subsystem and bank work subsystem and user authentication subsystem and system integration. The overall design of the "campus card" system, including the design of hardware and software design, module design, data design, planning and design of campus card and main business process. The author choose S50 chip when realizing the material function because it is good at consumption and function and it has mature apply. The paper proposed security strategy on the "campus card" system from two aspects of safety design and safety management system. Finally, the contents of this paper are summarized.
