One Intellective IC Card Reader Softeware And Hardware Design Based On ARM Processor

With the rapid development of new electronic technologies and bit contest of oil sale market ,PetroChina's oil sale should put on steam with IC card and carry out informative management in order to meet their demand"one card on hand, oil all over the country". this project is based on former POS machine with ARM processor to deal with modification which can read contactless card, deeply study contactless card's principle and COS, especially contactless card's advantage in function and reliability over contact card.Carrying out modification based on oil POS machine which can read contactless CPU card, successfully bring forward change from contact card interface protocol to contactless card interface protocol with hardware and software, reduce the cost that designs new equipment on a certain extent and meet PetroChina's demand of project progress. Successful tryout of this project bring forward many technical and engineering backgrounds about contactless card modification on all oil devices all over the country.By studying reliability of reading contactless card, establish better foundation on which contactless CPU card can be widely used in oil field, at the same time get more opportunitys and support of winning more devices' modification for the company.
