Differences between UHF and HF RFID electronic labels in application by RFID electronic label manufacturers 123

With the rapid development of Internet of things technology, the application of electronic labels has involved various fields. Today, let’s briefly understand the difference between UHF and HF RFID electronic tags in application:

The typical working frequency of high-frequency RFID tag is 13.56MHz, which is generally passive. When the tag and data exchange, the tag must be located in the near-field area radiated by the antenna of the RFID reader. The reading distance of high-frequency tags is generally less than 1m. High frequency tags are widely used in electronic ticket, electronic ID card, electronic locking and anti-theft (electronic remote control door lock controller), community property management, building access control system, etc. because they can be conveniently made into cards.

The operating frequency of UHF tags is between 860MHz and 960MHz, which can be divided into active tags and passive tags. When working, the RF tag is located in the far-field of the UHF reader antenna radiation field, and the coupling mode between the RFID tag and is electromagnetic coupling. The antenna radiation field of UHF reader provides RF energy for passive tags to wake them up. The reading distance of the corresponding RFID system is generally greater than 1 m, typically 4~6 m, and the maximum is more than 10 m. Reader antennas are generally directional antennas, and only RF tags within the directional beam range of reader antenna can be read/written. UHF tags are widely used in automatic identification of railway vehicles, container identification, and highway vehicle identification and automatic toll collection system because of their long reading distance and fast data transmission rate.

Characteristics of high frequency and ultra high frequency electronic labels:

High frequency tags are cheaper than UHF tags, save energy, have strong force to penetrate non-metallic objects, and the working frequency is not restricted by radio frequency control. They are most suitable for objects with high moisture content, such as fruits.
UHF has a wide range of functions and fast data transmission speed, but they consume energy and have weak penetration. There should be no too much interference in the operation area. It is suitable for monitoring items transported from the seaport to the warehouse. Moreover, the price of UHF system is relatively high, which is generally about 10 times that of HF system.
The difference between UHF and HF RFID electronic tags in application is shared above. Shenzhen Donglai electronic technology RFID electronic tag manufacturer provides customized production of RFID tags, RFID electronic tags, RFID tags, RFID anti metal tags and UHF RFID tags.
