From the functional regularity point of view, RFID electronic tags are mainly divided into four categories: low frequency, high frequency, ultra-high frequency and microwave.

1. Low frequency:

Typical main requirements are 125KHz, 135KHz, etc. Generally, digital tags in this frequency band are non-aggressive, and energy provision and information transmission are carried out through inductive coupling. Mainly used in access control methods, chips, vehicle alarms and toys and games.

2. High frequency:

A normal main spec might be the 13.56 mhz RFID cards . Compared to very low regularity, it's faster to transfer. Typically used for identification validation, collection control, project management, etc.

3. UHF:

The popular main requirements are 433MHz, 868~950MHz. This frequency music group transmits vitality and information through electromagnetic waves. It actually applies to career fields such as logistics and providing sequence management.

4. Microwave:

The frequency music group used is above 1GHz, and the typical requirements are 2.45GHz and 5.8GHz. Microwave volume groups have properties similar to app and oversized consistency music bands, reading about 2 meters through long distances, albeit with a higher degree of sensitivity to settings. Generally used for baggage monitoring, object management, providing sequence management, etc.
