Passive RFID tags harvest energy from the RFID reader's signal via antenna coupling.  Our UHF RFID tags activate within milliseconds, bouncing back data up to 10-30m away - perfect for pallet tracking or retail inventory.

HF (13.56MHz): Short-range (Usually <10cm), excels in security (e.g., payment systems)

UHF (860-960MHz): Our specialty!  Long-range (1-30m) + bulk reading (600+ tags/sec).  Used in 80% of industrial applications like warehouse logistics with readers like Symo FR04 Pro
