What do LF, HF, and UHF stand for?

Just as your radio tunes in to different frequency to hear different channels, RFID tags and readers have to be tuned to the same frequency to communicate. They correspond to different frequency ranges of the RF spectrum. LF stand for Low Frequency (around 125 KHz), HF stands for High Frequency (˜ 13.54 MHz), and UHF stands for Ultra-High Frequency (850-910 MHz).
