Rfid Tag

An RFID tag is a small electronic device with a microchip and antenna that stores a unique identifier and communicates with an RFID reader using radio waves. In supply chain and manufacturing, tags are attached to items, cases, pallets, containers, raw materials, and assets so identity and movement can be captured automatically, often in bulk and without line-of-sight scanning.

On a shop floor, RFID tags are applied at source or receiving so parts and work-in-process are identifiable from origin through production stages, enabling item-level traceability and production monitoring. In warehouses, fixed portals and handheld readers automate receiving, put-away, pick confirmation, pack validation, ship validation, and cycle counts, which improves inventory accuracy and reduces manual scanning labor. For raw materials, RFID gives real-time stock visibility and faster picking by letting operators quickly identify bins, totes, drums, or bundles while preserving traceability through conversion steps. Because reads occur automatically when tagged goods pass gates, the technology supports shipment visibility, proof-of-delivery, and cross-dock flow control. In lean or JIT environments, RFID data drives replenishment triggers, sharper demand forecasting, and lower safety stock because inventory positions update more reliably than with manual methods.
