RFID UHF tags operates between ISM 860 – 960MHz and has read ranges up to approximately 10ft. UHF has become the most used option in Auto-ID applications due to its long read range and dropping costs. UHF does have more issues with interference, but a well designed system can overcome these problems. The RFID UHF tags has been validated by tests simulating simultaneous high temperature, high pressure stresses as well as in actual live well site for survivability and performance under the extreme conditions of pressure, vibration, temperature and chemicals of a well. UHF RFID is also well suited for mounting on label stock, making it the perfect item/container-level tagging option. RFID UHF tags are available in Metal, on Air, in ceramic, and Lock removable. UHF tags are embed with different IC types which opens option for different size of TID,EPC length, User memory were customers can choose based on economic level of project.
