| With the rapid development of electronic information technology, smart cards are now very popular in our life. Radio Frequency Identification card is becoming a new fashion in the application field of smart card, replacing the traditional contacting smart card. Such must lead to a conceptual revolution of human being's future lifeway by which Smart Card be the most important, most convenient and most indispensable tool in the 21st century.For the inconvenient and question of using checking on attendance system, the paper brings forward a checking on work attendance management system using monitor and smart card. The system is programmed using the programming interface of present smart card product. The system uses the object-oriented design method. It can not only work singly, but also can communicate with local area network of the enterprise. The system can satisfy the modern work demand, and simple operation, cost low, easy to maintain.The article's feature is that it stands out the emphases basing on presenting contactless smart card system in the round. The stress of the paper is the design and realization of contactless smart card reader which is discussed respectively from the hardware and the software. The hardware involves main control module, Radio Frequency module, antenna, communication module, alarming modules and so on. The software aspect is emphasis on the plan of the main program, the design of MF RC500 application and the realization of the function of the reader's outer operation. It also introduces the composing of soft management system, provides flow chart of software and source program. At last, it discusses some measures that how to improve the reliability of system.At last, all the work is summarized and a research prospect if the subject in future is promised. |
