Starting next month, the retailer will place removable "smart tags" on individual garments that can be read by a hand-held scanner. Wal-Mart workers will be able to quickly learn, for instance, which size of Wrangler jeans is missing, with the aim of ensuring shelves are optimally stocked and inventory tightly watched. If successful, the radio-frequency ID tags will be rolled out on other products at Wal-Mart's more than 3,750 U.S. stores.
Radio Frequency Identification (RFID) offers a number of potential benefits: traceability, inventory management, labour saving costs, security and promotion of quality and safety. However this technology raises privacy concerns.
Wal-Mart is demanding that suppliers add the tags to removable labels or packaging instead of embedding them in clothes, to minimize fears that they could be used to track people's movements. It also is posting signs informing customers about the tags.
