While RFID is a generic term encompassing different operating radio frequencies and standards, UHF is a frequency band covering 300MHz to 3GHz. UHF systems are known for generating long read ranges, up to 12m, whereas high frequency (HF) systems carry a much shorter read range, of approximately 1m. UHF allows for a faster data transfer rate, up to 20 times the range and speed of HF systems.
