Sensors integration in RFID tags for agricultural traceability

It is a bottleneck of transparency of the agricultural traceability system to acquire environmental parameter of agricultural products in the supply chain real-time and accurately. Radio frequency identification (RFID) technology has been a research hotspot in recent years as a new automatic identification technology. It is significant to combine RFID tag with sensor to the agricultural products traceability system. It can detect and record temperature, humidity and other important parameters, and it can be identified by wireless communication. The current development status of this kind of tag was reviewed both in China and other countries. The key technology is analyzed, and the existing problems and solutions are pointed out. It provides a reference for further research on RFID tags integrated sensors.
