Non-contact Rf Ic Card Technology Applications And Research

This paper introduces the basic principle and the application of the contactless 1C card technology. First, the paper describes the development and the status quo of the 1C cards. Then, the work principle of the radio frequency 1C card is discovered through studying the principium of the radio frequency technology. The paper analyzes the logic data structure of the 1C card and security performance supported by 1C cards. Point to the matters about the data transmission in radio frequency 1C cards, the ways to encode and modulate are provides, and the method to anti-collision is presented. The international standards about the radio frequency 1C cards - ISO/TEC 14443 are introduced too, it refers to the difference about the Type A and Type B standard. Whereafter , the forecast about the trend of the contactless 1C cards - contactless CPU cards is given, and the method to solve the power supply problem for radio frequency CPU cards is analyzed. At last, the paper researches the application of radio frequency 1C cards with the example of automatic fare collection (AFC) system, the work consists of the hardware and software design, and the whole system structure design. Especially designs the realization of the security performance and the data management. In the end of the chapter, a scheme that fit multi application with single card, which expands the system to the whole public transaction area were brought forward.
