The advantages and applications of UHF RFID electronic tags

As we all know, electronic tags are mainly divided into high-frequency electronic tags, low-frequency electronic tags, and ultra-high-frequency electronic tags according to frequency classification. Today we mainly understand the advantages and applications of ultra-high-frequency RFID electronic tags.

(1) Advantages of UHF RFID electronic tags;

It can identify high-speed moving objects, and can also read multiple objects at the same time, with the following advantages:

1. Strong penetrability and resistance to harsh environment.

2. Strong security and confidentiality.

3. Reusable, large data memory capacity.

(2) Standard protocol for UHF RFID electronic tags;

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 6C and 6D standards, namely ISO / IEC 18000-6C (63), ISO / IEC18000-6D (64), and the Chinese national standard GB / T 29768-, which was formally implemented in May 2014 in China. 2013

Three, UHF RFID electronic tag frequency band;

The global definition of UHF electronic tag frequency bands vary, for example:

1, China's frequency band 840 ~ 844MHz and 920 ~ 924MHz

2, EU frequency band 865MHz ~ 868MHz

3, Japan frequency band between 952MHz ~ 954MHz.

4, Hong Kong, Thailand, Singapore 920MHz ~ 925MHz

5, the frequency band of the United States, Canada, Puerto Rico, Mexico, South America is 902MHz ~ 928MHz

Fourth, the application of UHF electronic tags;

The UHF RFID market has a wide application scene, with the advantages of being able to read multiple tags at one time, long distance recognition, fast data transmission, high reliability and long life, and resistance to harsh outdoor environments.

Can be used for asset management, production line management, supply chain management, warehousing, anti-counterfeiting traceability of various items (such as tobacco, alcohol, medicine, etc.), retail, vehicle management, etc.
