Ultra High Frequency (UHF) RFID operates between 902-928 MHz in North America 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. UHF RFID is also well suited for mounting on label stock, making it the perfect item/container-level tagging option.
