RFID Frequency Guide: LF vs HF vs UHF
RFID systems operate across three main frequency bands - Low Frequency (LF, 125-134kHz), High Frequency (HF, 13.56MHz) and Ultra-High Frequency (UHF, 860-960MHz). Each frequency offers a different balance of read range, data speed and material tolerance. LF tags excel near metal and liquid but read only to ~10cm; HF/NFC tags reach ~1m and work with smartphones; UHF tags read up to 12m and support fast batch reading - the default choice for supply chain, retail inventory and logistics.
Why Choose IDrfid
LF 125-134kHz
Short range ~10cm, highly tolerant of metal and liquid, ideal for animal ear tags and access control.
HF 13.56MHz (NFC)
~10cm to 1m range, smartphone-compatible, the standard for NFC tags, payment and library.
UHF 860-960MHz
0-12m range with anti-collision batch reading, best for retail, warehouse and logistics.
Choosing the Right Band
Match frequency to read distance, surface material and application requirements.

Frequently Asked Questions
What is the difference between LF, HF and UHF RFID?
They differ in frequency and read range: LF (125kHz) reads to ~10cm and tolerates metal; HF (13.56MHz, includes NFC) reaches ~1m and works with phones; UHF (860-960MHz) reads up to 12m and supports fast batch reading for logistics and retail.
Which RFID frequency has the longest read range?
UHF 860-960MHz offers the longest read range, up to 12 meters, making it the standard for warehouse, supply chain and retail inventory tracking.
Which frequency works best near metal and liquid?
LF (125kHz) is most tolerant of metal and liquid. UHF tags need special anti-metal designs to read reliably on metal surfaces.
