How to choose electronic RFID tags

Radio frequency identification technology is one of the main methods of automatic data collection at present. Electronic tags are an indispensable part of radio frequency identification systems. However, in most cases, tags are not universal, but different electronic tags can be selected according to the requirements of the scene.

For example, the frequency band can be divided into LF, HF, UHF, 2.4G, 5.8G, etc. Different frequency bands have their own advantages and disadvantages. Low-frequency products have good penetrability, but the data transmission speed is limited and can be applied to animal management. High frequency (HF) is usually suitable for payment and various identifications due to reading distance and protocol limitations. Ultra-high frequency (UHF) can be read from a long distance. The most important feature is one-time batch reading, but it is susceptible to environmental interference, especially metals and liquids. It is mainly used for clothing retail and logistics storage. 2.4G and 5.8G active products have stable signal, large data storage capacity, and extremely long reading distance, but the battery durability and high price are the shortcomings of the application.

The use environment of products in the same frequency band is different, so packaging and installation methods are also very different. Usually take HF as an example, using PVC cards for payment and identity management. In anti-counterfeiting tracking, you can choose fragile paper or coated paper. Due to the particularity of the problems faced by customers, there are certain differences in the same application of products in the same frequency band. For example, when the HF fragile label is tracking milk powder, if the surface of the milk powder can is made of plastic material, it can be directly pasted. If it is metal material, consider adding a layer of absorbing material.

Generally speaking, the various requirements of the frequency band characteristics, application schemes, performance indicators and installation methods of RFID tags will affect the standardization of radio frequency identification. Therefore, the customized development of radio frequency identification electronic tags is a key factor in determining the success of radio frequency identification system applications.
