RFID radio frequency identification technology is a non-contact automatic identification technology, non-contact two-way data communication through radio frequency, the electronic tag or radio frequency card to read and write, so as to complete the data communication between the reader and the tag, to achieve the purpose of identification and data exchange. The basic components of RFID system include RFID electronic tag, reader, radio frequency antenna, application software, is an automatic identification system using radio frequency identification technology for data acquisition and transmission. After 20 years of development, UHF RFID, because of its advantages of remote identification and low cost, has been widely used in retail, logistics warehousing, books and archives, anti-counterfeiting traceability and many other applications, only 2022, the global shipments of more than 30 billion, and maintain a continuous growth trend. From the perspective of application fields, the global UHF RFID tags and systems in the apparel retail industry has taken the lead in the application outbreak, becoming the pioneer of industry growth, and then, the global UHF RFID multi-scene application outbreak, in addition to the apparel retail industry, in intelligent manufacturing, automotive electronic identification, textile washing, medical, library and other fields of application are also rising rapidly. According to the current industry demand, the future development of China's UHF RFID has the following three trends. 1.The market size is growing:  RFID technology is the key technology of the "Internet of everything". In the future, the global RFID industry market size will continue to grow, and UHF RFID is the fastest growing area, and China will be the fastest growing country. 2.The application field is more extensive:  At present, UHF RFID is widely used in the clothing industry. With the development and popularization of technology, UHF RFID will continue to penetrate into intelligent manufacturing, automotive electronic identification, textile washing, medical and other fields. At the same time, affected by the increasing shortage of global energy, residents' attention to the environment and other factors, oil and gas pipelines, power grids, automobiles, construction and other industries will also become the key areas of UHF RFID application development. 3.Products to multi-functional development:  In the future, the global UHF RFID technology will be combined with sensors, GPS, biometrics, from a single identification to multi-functional identification development, to achieve cross-field, cross-industry applications. All in all, RFID is a booming technology with huge market potential. The rapid development and wide application of RFID sensing technology has produced new solutions in different application fields, and has a very broad prospect for the rich sensing applications of the Internet of Things in the future.
