| The commercial bank has issued a large number of magnetic stripe cards, these cards information through data encryption, symmetric key key encryption algorithm is simple, simple, easily broken; magnetic stripe card reader card writing tools, tools in the market is also the existence of a large number of buy cheap and convenient; based on the above two points, the magnetic stripe card now copy crack, the crime rate is increasingly high, learn from the advanced experience of foreign financial card, we must issue financial IC card. The people's Bank of the request for the commercial bank, in January 2015 and gradually stopped the magnetic stripe card, issued a comprehensive financial IC card.In this paper, the commercial banks to issue financial IC card, the actual work needs to start, the system carried out the feasibility study, needs analysis, system design, functional testing and performance testing, etc.. In the early stages of preparation, a large number of documents and materials, and the latest research results of the domestic and foreign, were consulted. The demand analysis stage of the business needs of the collection and analysis of sufficient, and for business personnel jointly completed a feasibility analysis report and specification of software requirements specification, and through rigorous evaluation line business department. Through the detailed description and analysis of business requirements, this paper presents the functional requirements of the system, and the data modeling, the E-R model is generated, the system design and the main functional modules of the detailed design and implementation, including template parameter configuration management, business card application management, business card data management, business card data security testing, business card printing and card management, etc.. The test scheme is given for each function module, and the function and performance of the test plan are tested.The biggest feature of the system is the service of the plug-in and standardization, which is the focus of the design phase of the work, but also our design principles. Under the principle of service and standardization design, the financial IC card data preparation subsystem is based on unified planning and unified management, in order to ensure that the entire system of a variety of software and hardware are in line with the relevant international standards, domestic standards, to ensure that the business, function and standardization, so as to achieve the standardization and management of service efficiency. System to provide a perfect service functions, covering the entire financial IC card life cycle, simple and efficient operation.The development standards of the financial IC card data preparing subsystem follow the latest standards of the people's Bank of China(PBOC3.0), which can meet the financial needs of the Bank of Xi'an. In the business card data template, the system has been fully reserved, which provides a good support for the expansion of the late card data. According to the latest research situation, the algorithm(for example, the national secret algorithm) and industry application(for example: public transportation, electricity, smart Park card, subway, etc.) is the new trend of the future development of the financial IC card industry, the latter can be a step to the two directions of research, continuous optimization and upgrading data preparation subsystem. Commercial banks in science and technology sector in the above two directions to continue to develop research, and constantly update the industry application, improve the user experience, so that their products more competitive. |
