RFID

RFID (Radio-Frequency Identification) is a wireless identification technology that allows tags (passive or active) to be read at distance without line-of-sight. RFID has become central to modern warehouse operations — enabling rapid case/pallet scanning, gate reading without manual barcoding, real-time inventory visibility, and item-level tracking.

Common frequencies: LF (low frequency, very short range, e.g., animal tagging), HF (e.g., NFC), UHF (long range, dominant in supply chain). Standards include EPC Gen 2 (UHF). Modern WMS platforms support hybrid barcode/RFID workflows so warehouses can adopt RFID incrementally.
