The design is based on the radio frequency technology as the core, to single-chip microcomputer as the controller of contactless IC card reader in expense system application. The paper introduces the hardware composition, software data processing. Non contact type IC card charging controller is a set of measurement functions and control functions of the device, is a use of modern microelectronic technology, modern sensor technology, non-contact IC card technology the use of water metering and water use data transfer and settlement transaction model. Firstly, this paper introduces the radio frequency identification technology and radio frequency card system overview, a detailed description of the non-contact radio frequency card structure, principle and Mifare1RF card and reader communication. Mainly introduces the radio frequency card reader hardware circuit design, including the design of MCU and MF chip RC500read and a connection between the control mode; MF RC500and connected between the antenna control display circuit module; design; water detection and electromagnetic valve control design; balance deficiency alarm and display circuit design of IC card. Software is the main content of RF card read and write operations program design and development, gives the terminal reader main program and each function module of the software design and the overall process, each branch of the process. Finally, on the subject of the work are su
