In recent years, with the increasing application of RFID technology in life, some technology companies combine UAV and RFID technology to improve the intelligent degree of UAV. UAV delivery has become a trend, Amazon, SF are doing tests. In addition to delivery, UAV plays an important role in many applications. UAV can read data during flight.

The Cal Poly research project found that UAVs using RFID readers can read tags attached to steel drills or utility pipes with 95% to 100% accuracy. The oil field usually needs to store thousands of pipe fittings (steel pipes for drilling operations), which are stored in different areas of the oil field, so inventory management is a very time-consuming work. Using RFID technology, when the RFID reader is within the scope of the items marked by the electronic tag, it can read.

However, in a large storage site, it is not practical to deploy fixed readers, and it is also time-consuming to use handheld readers regularly. By attaching RFID tags to dozens of pipe caps or pipe insulators, UAVs attached with UHF readers can usually read passive UHF RFID tags at a distance of about 12 feet. This solution not only solves the error of manual management, but also greatly improves the efficiency of work. However, in large storage areas, customers need to arrange a special person to "look after" the UAV, so as to replace the battery in time.

MIT's research team realized a more convenient inventory search by combining RFID technology with UAV. Compared with bar code, the information contained in RFID tags can be changed more widely and easily, and it is cheaper.

The UAV equipped with RFID card reader can replace the people in inventory and finish the work faster with less trouble. A person needs a ladder or elevator to enter the high box, which can be easily reached by UAV. UAV can be programmed to navigate the space independently, and they are more accurate and efficient than manual management in performing large-scale repetitive tasks.

By equipping the drone with a tiny relay, it's like a Wi Fi repeater. The UAV receives the signal from the remote RFID reader and then forwards it to read the nearby electronic tags. Because the relay is very small, it means that smaller UAVs can be used, plastic parts can be used, and it can adapt to a narrow space without the risk of personal injury. This not only eliminates the additional RFID reader, but also allows small UAVs to do the same work as large UAVs.

The combination of RFID technology and UAV can manage inventory and coordinate supply chain, and benefit from RFID deployment in warehouse. RFID UAVs help workers improve efficiency, reduce labor costs, optimize inventory levels, and track assets.
