Radio Frequency Identification (RFID) technology has been widely used in many fields such as industrial automation, commercial automation, and transportation control management. More and more research is beginning to study ultra-high frequency (UHF) RFID systems to achieve long-distance, high-efficiency, and low-cost features of the system. Because RFID has the advantages of non-contact, low cost, high anti-counterfeiting and mass production, and has low cost, it has gradually replaced the traditional two-dimensional bar code.
