Research And Implementation Of RFID Smart Price Input System

In recent years, with RFID technology (Radio Frequency Identification, RFID) ripening, it has been strongly advocated and popularized by the world government. RFID technology research has changed from the pure technology research to the real application. Combining RFID technology with industry characteristics to explore new models of RFID application has become the focus of the study for all research institutions and relevant manufactures. Until now, RFID has widely used in transport, access control, personal management. However, in domestic and aboard, seldom research can be found about RFID used in restaurant.This paper mainly tries to solve the problems of the slow payment in fast-food industry by using a new quick payment method based on RFID technology. The core of the study is RFID Smart Payment Tool using which to write the vegetable price into the service plates’ tags. The equipment consists of RFID module, display module, keyboard operation module and power module. This paper mainly introduces the work of the RFID radio frequency identification technology, quick payment system, etc. Basing on the above technology, this paper puts forward the design of hardware and firmware of the RFID Smart Payment Tool.
