Wal-Mart is to pilot item level tracking on jeans. Wal-Mart has been using RFID for pallet and container tracking for some time and according to some sources this has reduced the number of stock-outs by 30%. Wal-Mart has adopted a very sensible approach and has attached the tags to the outside of the jeans and made it easy to remove. Wal-Mart was a early adopter of RFID for pallets and I would expect to see other companies like Target to announce their own projects in the near future.
