A radio frequency identification (RFID) tag is used to identify pallets, products or individual parts or components. RFID tags, similar to bar codes, create a living bill of material that is scanned throughout the delivery process. As an example, RFID devices can help companies trace food products. The tag is assigned to bags of produce in the field, the boxes the bags go in and finally the loaded pallets. That same RFID product tag is then scanned throughout the supply chain, making it easy to trace food in the event of a recall.
