www.cse.wustl.edu3.2 Frequency Bands RFID tags fall into three regions in respect to frequency: Low frequency (LF, 30 - 500kHz) High frequency (HF, 10 - 15MHz) Ultra high frequency (UHF, 850 - 950MHz, 2.4 - 2.5GHz, 5.8GHz) Low frequency tags are cheaper than any of the higher frequency tags. They are fast enough for most
