What is Radio Frequency Identification (RFID)? Provide four examples or scenarios of how RFID can be used to aid in supply chain management
RFID aids in inventory management by making it easier to track inventory in the supply chain. It can synchronize information and physical flow of goods across the supply chain from manufacturers to retail outlets and to the consumers. Moreover, it is also very useful for tracking returned goods through the supply chain and to prevent counterfeit. For examples,
a . Materials management: As supply vehicle enters the warehouse, the fixed-portal RFID reader positioned at the entrance reads the tags on the pallets or individual items to provide handling, routing, and storage information of the incoming goods, and inventory status can be updated automatically.
b. Manufacturing: An RFID tag can be placed on the unit being produced so that specific customer configurations can be incorporated automatically during the production process. This is invaluable in a make-to-order environment.
c. Distribution center: As the logistics vehicle arrives at the loading dock, the fixed-portal RFID reader communicates with the tag on the vehicle to confirm that it is approved to pickup goods. When the loaded vehicle leaves the dock and crosses the portal, the reader picks up the signals from the tags to alert the RFID software and ERP system to update the inventory automatically and initiate an advanced shipping notice (ASN), proof of pickup, and invoices.
d. Retail store: As delivery vehicle enters the unloading dock, the fixed-portal reader picks up the signals from the tags, and the RFID software application processes the signals to provide specific handling instructions and initiates automatic routing of the goods. RFID reader can also be placed on the store shelf to trigger automatic replenishments when an item reaches its reorder point. Moreover, inventory status can be updated automatically in real time at any stage of the supply chain, and handheld readers can be used to assist in cycle counting.
