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
