Based On The Mf Rc500 Reader Research And Design,

The contactless card which is also named Radio Frequency Card,is a new developed technology of the world in recent year.It is a product of the radio frequency identification technology and the IC card technologh.and it transmit energy and data through wireless mode,and it solves the problems of non-energy and non-contact.The information is storged andmanaged through the integrate circuit in the card.The memorizer in the card is disport several subarea,and it hold differ application in order to attain many use of one card,moreover the high safety , long life-span and facility maintenance of the card make it a new foce suddenly rise in the area of IC card and become prevail pet of IC card. The contactless card abroad apply in finance, bus system, capacity building and social security.This thesis use MF RC500 CMOS chip of Philips company and introduce a design of contactless reader through hardware and software.It can meet many request through development of periphery circuit and program of software.Many contents of this thesis are as follow.1. RF interface circuit and antenna design have been finished according to the standard of ISO/IEC14443.2. The siglechip circuit and the anti-jamming protect have been finished3. To satisfy the demand of data security confidentiality etc.,a scheme is given. In ccordance with the given solution,CRC verification algorithm and RSA Enctyption algorithm are given.4. A set of the communication protocol of the card system is analyzed.Following the protocol,the operation process of the whole card had been analyzed.
