Q: What is RFID and its types?

RFID tags can be grouped into three categories based on the range of frequencies they use to communicate data: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF). Generally speaking, the lower the frequency of the RFID system, the shorter the read range and slower the data read rate.

Answer

The three main types of radio frequency identification tags are low frequency (LF), high frequency (HF), and ultra-high frequency (UHF). In general, the read range and data read rate of an RFID system are negatively correlated with its frequency.
