At present, RFID electronic tags have been widely used and promoted. RFID is classified according to the working frequency of the RFID system. It can be divided into three categories: low frequency, high frequency and ultra high frequency. Low frequency, high frequency and ultra high frequency are actually RFID electronics. Some categories in labeling technology. So do you know what UHF, LF, and HF RFID electronic tags are? Let's take a look at them together.

UHF, low frequency, and high frequency RFID electronic tags are also some classifications in RFID electronic tag technology. RFID electronic tags are not uncommon in our lives. So what is UHF, low frequency, and high frequency RFID electronic tags? Please see below.
1. What is UHF RFID electronic tag.
UHF RFID electronic tags can provide an unprecedented and almost perfect solution for the supply chain, that is, the company will be able to know the location information of each product at any point in their supply chain in time.
UHF RFID electronic tags mainly have the following characteristics:
1. Data storage time is up to 10 years.
2. UHF has a wide range of action. The most advanced Internet of Things technology now uses UHF electronic tag technology.
3. Fast data transmission speed, up to 170 sheets per second per second for a single label reading rate.
4. The UHF electronic tag has a unique ID number in the world, which has strong security and confidentiality and is not easy to be cracked.
5. UHF electronic tags are flexible and can be easily identified.
6. It has a high data transmission rate and can read a large number of electronic tags in a short time.
7. Anti-collision mechanism, suitable for multi-tag reading, multiple electronic tags can be read in batches at a time.
8. The antenna of the electronic tag is generally long and tag-shaped. The antenna has two designs of linear and circular polarization to meet the needs of different applications.
2. What are low-frequency and high-frequency RFID electronic tags?
Low-frequency RFID electronic tags generally adopt the principle of electromagnetic coupling, and the typical high-frequency operating frequency is 13.56MHz. Radio frequency tags in this frequency band, because their working principle is exactly the same as that of low-frequency tags, that is, they work in an inductive coupling mode, so they should be classified as low-frequency tags. On the other hand, according to the general division of radio frequency, its working frequency band is also called high frequency, so the two are often collectively referred to as high frequency tags.
Low frequency and high frequency RFID electronic tags mainly have the following characteristics:
1. The data transmission speed is slow.
2. The label storage data volume is less.
3. Low-frequency electronic tags have poor flexibility and are not easy to be identified.
4. The data transmission rate is low, and the electronic tags can only be read one to one in a short time.
5. Only suitable for low-speed, short-range recognition applications.
6. Compared with UHF electronic tags, the tag antenna has more turns and higher cost.
7. The reading distance is small. When transmitting data between the low-frequency tag and the reader, the low-frequency tag must be located in the near-field area radiated by the reader's antenna. The reading distance of low-frequency tags is generally less than 8 cm
8. Low-frequency electronic tags have poor security and confidentiality and are easy to be cracked.
