RFID electronic tags have been widely used. UHF, low frequency, high frequency RFID electronic tags are some of the classifications in RFID electronic tag technology. RFID tags are not uncommon in our lives. So what are UHF, low frequency, high frequency RFID tags? Low frequency, What are the characteristics of high frequency and ultra high frequency RFID electronic tags?
1. What is UHF RFID electronic tag.
UHF RFID tags are an unprecedented, near-perfect solution for the supply chain, meaning that companies will be able to keep abreast of the location of each item at any point in their supply chain. UHF RFID electronic tags mainly have the following characteristics:
 Data retention time is up to 10 years.
 UHF has a wide range of functions, and the most advanced IoT technology uses UHF electronic tag technology.
 The data transfer speed is fast, and the single-tag read rate is 170 frames per second per second.
 UHF electronic tags have a unique ID number in the world, which is safe and confidential and difficult to crack.
 UHF electronic tags are flexible and easily recognizable.
 has a high data transmission rate and can read a large number of electronic tags in a short time.
 Anti-collision mechanism, suitable for multi-tag reading, single-time batch reading of multiple electronic tags
 The antenna of the electronic tag is generally a long strip and a label. The antenna is available in both linear and circular polarization to meet the needs of different applications.
Second, what is a low frequency, high frequency RFID electronic tag.
Low-frequency RFID electronic tags generally use the principle of electromagnetic coupling, and the high-frequency typical operating frequency is 13.56MHz. The RF tag in this band is classified as a low-frequency tag class because it works in exactly the same way as the low-frequency tag, that is, it works by inductive coupling. On the other hand, according to the general division of the radio frequency, the operating frequency band is also called high frequency, so they are often collectively referred to as high frequency tags.
Low-frequency, high-frequency RFID electronic tags mainly have the following characteristics:
 The data transfer speed is slow.
 The amount of data stored in the tag is small.
