| Abstract: | At present,the IC card is a kind of intelligent card applying to visit controlling and electronic note extensively. The article has provided a kind of simplest application method for IC card SLE4442 in the single chip computer system. And a simple control system for intelligent contact-type IC card is presented,which is capable to read/write the logleally encrypted memory card SLE4442. With some adaptations in software and peripheral circuits,the system could be easily used in various fields,such as power charging system and gas charging system. The paper also has introduced the characteristic of the SLE4442 chip, the structure of storage,and the most essential connection between SLE442 chip and single chip processor. Moreover,the method how to use the system, the problem of programming, and the flow chart of the system program of some interrelated commands has also been illustrated in the paper. |
