Abstract: For keeping salt safe, this paper presents a tracking and traceability system. It achieves the system with Radio Frequency Identification(RFID) technology, and RFID is used to collect data for tracking and tracing function. The system can automatically collect, store data, and display in a good way. Experimental results show that this system can manage salt efficiently, conveniently and stably and keep salt product safety.

Key words: Radio Frequency Identification(RFID), tracking, traceability, salt, food safety, low frequency
