Aiming at the problem that the current RFID reader cannot be carried around and realizes the remote IC card reading and writing operation, the GPRS wireless network is used as the carrier of data transmission to realize the development of wireless RFID reader. The μC/OS-Ⅱ embedded real-time operating system is used as the software platform of the reader terminal, and the issuance, value-added, consumption, operation record query and summary, data collection and wireless transmission of IC cards are realized on the ARM7 series microprocessor LPC2148. The dynamic key encryption algorithm is used to well ensure the data security of the IC card. The application results show that the RFID reader is stable and reliable, has a fast response speed, is easy to install and operate, and is easy to carry. It has certain practicality and promotion value.
