RFID technology and application Work for Walmart
At the receiving port of the Wal-Mart distribution center, when the goods pass through the door,
the RFID reader automatically completes the inventory and enters the Wal-Mart database; after the
goods are directly sent to the conveyor, the distribution center distributes the goods according to
the types and quantities of goods required by each store.
There is no need to manually adjust the orientation of the products; when the goods are loaded on
the way to the stores, the GPS positioning system or the RFID monitoring points along the way can
accurately understand the position and completeness of the products, so as to accurately predict
the arrival of the goods. Time; After arriving at the store, the truck directly installs the RFID reader
through the receiving port, the goods are counted, or sold directly or temporarily stored in the store
warehouse, the inventory information in the store database is Reduced, the shelf with RFID reader
automatically reminds the clerk also updated; to replenish the goods; the goods that are randomly
placed because the customer changes the purchase decision can also be easily found and returned
by the clerk through the RFID reader covering the entire store; After the customer purchase, only
the cart needs to be installed from the aisle with the RFID reader installed.
Through, the statistics of the goods are automatically completed; the general customers can choose
traditional settlement methods such as cash and credit cards, and customers who use the RFID tag
settlement card can choose RFID checkout, that is, the system automatically deducts the money, and
the trouble of queuing payment is greatly reduced. Even completely eliminated. Once the goods enter
the various places covered by the RFID reader, the RFID system automatically assumes the function
of EAS (Electronic Commodity Monitoring), thereby effectively preventing theft of the goods.
