1. Operating frequency
- The operating frequency range of UHF RFID tags is usually between 860 MHz and 960 MHz.
- HF RFID tags operate in the frequency range of 13.56 MHz.
2. Communication distance
- UHF tags usually have a longer communication distance, which can reach several meters to more than ten meters.
- The reading distance of HF tags is usually within 10 cm.
3. Reading speed
- Due to the difference in frequency and communication distance, UHF tags usually have a faster reading speed.
- This makes UHF tags more suitable in scenarios where a large number of items need to be identified quickly.
4. Anti-interference ability
- UHF RFID tags are relatively weak in the presence of various interference objects such as metal and liquid. Due to the high operating frequency of UHF tags, the signal is easily interfered when it comes into contact with metal or near liquid, which may cause the signal to weaken or be lost.
- High-frequency RFID tags have strong anti-interference ability and can keep the signal stable and reliable when in contact with metal or liquid. This makes high-frequency tags more suitable for scenarios where identification and communication are required in environments with interference.
5. Application areas
- UHF RFID tags usually have a longer communication distance and can achieve long-distance reading of multiple meters to more than ten meters. Therefore, they are widely used in scenarios where a large number of items need to be tracked and managed, such as logistics, supply chain management, and large-scale asset tracking.
- HF RFID tags are used for identity authentication, access control, and payment systems due to their shorter reading distance and strong anti-interference ability. These scenarios have higher requirements for higher security and shorter-distance communication.
Therefore, it is very important to choose the right tag technology according to your specific needs and working environment. UHF RFID tags are suitable for applications that require long-distance reading and large-scale item management, while high-frequency RFID tags are suitable for scenarios with higher requirements for security and shorter-distance communication.
