5 common RFID tag classification, you have seen several？

With the advent of the mobile Internet era with 5G technology as the benchmark, the interconnection of all things and the perception of all things are gradually becoming a reality. As an important supporting technology for the Internet of Things to perceive the outside world, RFID technology is closely related to our daily work and life, especially in retail scenarios. has been widely used. So do you really understand RFID tags? In which scenarios can RFID tags be applied?
 

RFID tags can be divided into active RFID tags and passive RFID tags according to the presence or absence of energy supply. The "source" in the active RFID tag refers to the power supply. As the name suggests, it is an RFID tag powered by a battery. This type of tag generally has a long reading distance, so it is more suitable for long-distance personnel positioning; the passive RFID tag is It can be understood as a tag without battery power supply. Compared with active, this type of tag is characterized by small size, light weight, low cost and long life.

 

According to the different working frequency bands of tags, it can be divided into four types: low-frequency RFID tags, high-frequency RFID tags, ultra-high-frequency RFID tags and microwave tags. The low-frequency RFID tag looks very unique in appearance and has more personality. The operating frequency is generally 125.124KHz, the recognition distance is relatively short, and there are many special-shaped packages.


Compared with low-frequency RFID tags, the typical working frequency of high-frequency RFID tags is 13.56MHz. The line type of such tags is very neat, and the reading distance is within 1 meter. ID cards are all application examples of high-frequency RFID tags;


According to the working frequency band, the third type is the UHF RFID tag. The line type is full of artistic sense. Its working frequency band is 860-960MHz, and the recognition distance can reach more than 10 meters. The RFID handheld reader can perform batch operations on RFID electronic tags, which is very suitable for warehouse entry and exit management and daily inventory work in stores.

The RFID tag with the highest frequency band is called microwave tag, and the working frequency band is 2.45GHz and 5.8GHz. The most typical representative of this type of tag is the ETC non-stop toll card on our highway.
 

According to chip storage classification, tags can be divided into read-only RFID tags and read-write RFID tags. There is no difference in appearance between the two. The difference is that read-only RFID tags can only be written once, while read-write RFID tags are Can be erased repeatedly.
 

According to the different packaging materials, it can be divided into flexible self-adhesive RFID tags and rigid RFID tags. Flexible self-adhesive RFID tags are often encountered in our lives. They look like a piece of self-adhesive, but actually contain chips. They are more common in high frequency and ultra-high frequency, and are mainly used for product anti-counterfeiting, Various application scenarios such as logistics traceability and identity recognition; compared with flexible RFID tags, rigid RFID tags are mainly made of PCB material, ceramic material, and have a hard texture, so they are called rigid RFID tags.
 

The above are all classified according to the different attributes of the RFID tag itself. Finally, we will discuss how to classify different application scenarios?

The scenarios combined with practical applications mainly include new retail flags, anti-transfer and fragile labels commonly used in the traceability field, library RFID tags, and the most used tag integrated RFID tags in the clothing field, washing RFID tags... …
