Overview
UHF RFID reading systems can reach more than 12 meters, have very fast data transmission and are very sensitive to interference. They are more sensitive to interference from metals, liquids, and electromagnetic signals. UHF tags are much cheaper to manufacture, and as such are commonly used in retail inventory tracking, pharmaceutical anti-counterfeiting.
UHF RFID readers are available in a variety of configurations including portable devices, fixed readers, and readers integrated into conveyor belts or other production line technology. An embedded processor is often used to decode the data once the antennas have captured the RFID tag's signal.
UHF RFID readers operate at 840–960 MHz. Its expanded read range compared to HF NFC readers allows one reader to interact with multiple tags at once.
