104 Wal-Mart stores, the company has installed RFID readers at the receiving docks at the back of the building, near the trash compactors and between the back room and the retail floor.
o For the cases of goods that are shipped to the stores with RFID tags, Wal-Mart records their arrival by reading the tag on each case and then reads the tags again before the cases are brought out to the sales floor.
o By using sales data from its existing point-of-sales system, which is not using RFID, Wal-Mart subtracts the number of cases of a particular item that are sold to customers from the number of cases brought out to the sales floor.
o When a case is brought out to the sales floor, the system records that it's being put out on the shelves.
o When the case is read at the trash compactor, the status within the system is changed to "on shelf."
o Suppliers can get updates on the location of their goods within 30 minutes of the goods movement from one part of the store to another with a 98%read rate.
By this system the company's operation will be more easier to maintain the goods .
