The work aims to introduce RFID technology and review the progress of its application in other aspects such as intelligent packaging and food supply chain traceability, with a view to providing a certain theoretical basis for the development of food quality control. The composition, classification, working principle of RFID system and the advantages of this technology were introduced. The potential application of RFID technology for monitoring temperature, humidity, pH, and gas content within food packaging was analyzed. An overview of advances in the traceability of RFID technology throughout the food supply chain (production, processing, storage and distribution) was provided. The problems faced in the practical application of RFID technology and the future direction of development were discussed. Through a comprehensive overview of the application of RFID technology in intelligent packaging, food traceability and other aspects, it shows that RFID technology has a wide range of application prospects in the field of food, which is of great significance to food quality control.
