UHF (Ultra-High Frequency) RFID operates in the 860–960 MHz range and is widely used for fast, long-range, and bulk identification. It offers superior read distances (up to 10 meters) compared to LF and HF RFID. UHF RFID is suitable for logistics, inventory management, retail, and vehicle tracking. Labels and tags used in UHF systems come in various forms like paper labels, hard tags, on-metal tags, and windshield labels. These tags are typically passive, meaning they don’t require a battery and are activated by the reader’s signal. UHF labels are thin, flexible, and ideal for items like cartons, pallets, and apparel. Hard tags are rugged and used for industrial or reusable assets. Proper tag placement and orientation are crucial for reliable performance. Environmental factors like metal surfaces and liquids can affect read accuracy, requiring specialized tag designs. UHF tags can be encoded with item-level data like product ID, batch, and expiry. Label durability depends on material and adhesive quality. RFID labels often include printed barcodes or human-readable info. They reduce manual scanning and improve real-time visibility. Integration with ERP or WMS enhances automation. UHF RFID enables high-speed, contactless, and multi-tag reading, making it a key enabler of smart supply chains.
