Research And Development Of Contactless Radio-Frequency Card Application System

The technology of radio-frequency identification is a new auto-identification technology in recent years. It can realize radio intercommunication between Contactless Smart Card and reader-writer, to complete object identification and data exchange by radio way. At the same time, it can realize the multi-objective identification and the movement target identification.The appearance and development of the Contactless Radio-Frequency Card will certainly further to impel the revolutionary transformation of the human payment system. With our country's"golden card project"starting, the technology of radio-frequency identification will more and more apply in the Each profession, especially in commercial finance automation, industrial automation, transportation, military national defense, and so on.Based on the research of the related theory and the technology of the Radio-Frequency Card, this thesis designs a whole system which is used to manage the Contactless Radio-Frequency Card. At first, this thesis unifies the domestic and the foreign research and development tendency of radio-frequency card, briefly introduces the Contactless Radio-Frequency technology, embarks from the Contactless Radio-Frequency composition structure, basically analyses the basic principle and its involved essential technology of the Radio-Frequency card system. Second, the thesis emphatically analyses the Contactless Radio-Frequency Card system's software and hardware development, concretely introduces the MCU and the radio frequency module characteristic of the hardware design, detailedly analyses each part of hardware function (radio-frequency identification module, display circuit, alarm module, 485 communication module, and so on) and the circuit design of the terminal reader-writer. Based on the hardware design, the thesis concretely elaborates the terminal reader-writer software design process, produces the software design of the terminal reader-writer's master routine and various functions module, and unifies the design of the terminal reader-writer to develop the radio-frequency card management software as the host management software, and detailedly introduces the database management and serial communication.This thesis also makes the detailed discussion to the systematical security of the Contactless Radio-Frequency Smart Card system, does the thorough research to the authentication process of the Contactless Radio-Frequency Smart Card. This thesis finally makes the summary and the forecast to the topic, pointes out the improvement to the system.This thesis takes the actual project development as an example, comprehensively elaborates the involved knowledge of the Contactless Radio-Frequency Smart Card system, pointes out the emphasis and the difficulty, thus impels and accelerates the widespread application of the Contactless Radio-Frequency Smart Card.
