In this paper, we conducted the research on RFID technology in the application of parking management system. The system adopts the scheme of RFID technology combined with background application software, whose foreground uses Visual basic 6.0 to carry on the application procedure development, and background carries on the data administration work with access database. It collects ID information by RFID module, and then uses computer software technology to charge fees even though vehicles do not stop. In that way the system achieves the automation of management and charge. In addition, this paper has also introduced RFID hardware components, operating principle, installation method of readers and control equipment (PC) in the parking site, system software design, development processes of software data acquisition in detail.
