We all know that for the RFID system to work normally, the reader and the electronic tag must be “same frequency”, otherwise they cannot communicate and identify. Different working frequencies also have differences in working principle, recognition distance and performance. Internationally, RFID is divided into different frequency categories such as low frequency LF, high frequency HF, ultra high frequency UHF and microwave. The working principle of each frequency band RFID has certain Among them, the working principle of LF and HF is electromagnetic coupling, while the RFID of UHF and microwave band is the way of electromagnetic emission. The difference in working frequency leads to different application scenarios.

Low-frequency RFID, referred to as low-frequency tags, low-frequency electronic tags have poor security and confidentiality. Its operating frequency range is 30kHz ~ 300kHz. Typical operating frequencies are: 125KHz, 133KHz (there are also other frequencies close to it, such as TI uses 134.2KHz). Low-frequency tags are generally passive tags, and their working energy is obtained from the radiation near-field of the reader coupling coil through inductive coupling. When transmitting data between the LF tag and the reader, the LF tag must be located in the near-field area radiated by the reader antenna. The reading distance of low frequency tags is generally less than 1 meter.

Typical Applications,
Animal identification, container identification, tool identification, electronic locking anti-theft (car key with built-in transponder), etc. The international standards related to low frequency tags are: ISO11784/11785 (for animal identification), ISO18000-2 (125-135kHz). Low-frequency tags have a variety of appearance forms, and the appearance of low-frequency tags used in animal identification includes: collar type, ear tag type, injection type, pill type, etc. Typical application animals are cattle, homing pigeons, etc.

Main Advantages,
The tag chip generally adopts ordinary CMOS technology, which has the characteristics of power saving and low cost; the working frequency is not restricted by radio frequency regulation; it can penetrate water, organic tissue, wood, etc.; it is very suitable for short-distance , low-speed, and less data-requiring recognition applications (for example: animal recognition), etc.

Disadvantages,
Tags store less data; only suitable for low-speed, short-distance identification applications.
