The baggage tracking system of global airlines has developed to the present and is relatively mature. However, even under the most ideal conditions, the barcode system can only correctly read 8 to 9 pieces of baggage, which means that airlines have to Continuously invest a lot of time and energy in manual operations to transport the sorted baggage to different flights. At the same time, because bar code scanning requires high directionality, this also adds extra workload to airport staff when performing bar code packaging.

RFID radio frequency identification technology is generally regarded as one of the most promising technologies in the 21st century. It is a new technology that has caused changes in the field of automatic identification after barcode technology. Its non-line-of-sight, long-distance, low directivity, fast and accurate wireless communication capabilities have been increasingly focused on the airport baggage automatic sorting system. Finally, in October 2005, IATA (International Air Transport Association) unanimously passed a resolution to adopt UHF (ultra-high frequency) RFID strap-on tags as the only standard for aviation luggage tags.

The RFID baggage automatic sorting system is to paste RFID electronic tags on the randomly checked baggage of each airplane passenger. The electronic tags record the passenger’s personal information, departure port, arrival port, flight number, parking position, departure time and other information; baggage flow Electronic tag reading and writing equipment is installed on each control node of the, such as the sorting, loading area, and baggage claim area. When the baggage with tag information passes through each node, the RFID reader will read the information and send it to the database. Realize the information sharing and monitoring of baggage in the whole transportation process.
