1. Advantages of UHF RFID tags;
It can recognize high-speed moving objects, and can also read multiple objects at the same time, which has the following advantages:
1). Strong penetration and resistance to harsh environments.
2). Strong security and confidentiality.
3). It can be used repeatedly, and the memory capacity of data is large.
2. UHF RFID electronic label standard protocol;
At present, the common UHF RFID air interface protocols in China include international standards, national standards, industry standards, and enterprise standards.
The most popular standards are the 6C and 6D standards, namely ISO/IEC 18000-6C(63), ISO/IEC18000-6D(64), and the Chinese national standard GB/T 29768- 2013
3. Ultra-high frequency RFID electronic label frequency band;
The global coverage of UHF electronic tag frequency bands is not the same, for example:
1). China's frequency bands 840~844MHz and 920~924MHz
2). EU frequency band 865MHz~868MHz
3). The frequency band in Japan is between 952MHz and 954MHz.
4). Hong Kong, Thailand, Singapore 920MHz~925MHz
5). The frequency band of the United States, Canada, Puerto Rico, Mexico, and South America is 902MHz~928MHz
4. The application of ultra-high frequency electronic tags;
The market application scenarios of UHF RFID are quite broad, and it has the advantages of being able to read multiple tags at one time, long identification distance, fast data transmission speed, high reliability and lifespan, and resistance to harsh outdoor environments.
