RFID are roughly classified into LF band (~135kHz), HF band (13.56MHz), UHF band (900MHz band), Microwaves (2.45GHz) on the basis of frequencies of used radio waves.
Although the reachable distance of radio wave depend on the conditions related to the antenna size and the signal strength, generally speaking it is known as “”LF band ( ~10cm), HF band ( ~30cm), UHF band ( ~5m), and Microwaves ( ~2m).
