It's an ongoing concern of ours. It was one of the big themes of our annual report about two years ago.
Certainly as RFIDs spread through the marketplace we will be monitoring them very closely. Right now we understand they're being introduced into the merchandise supply chain at the pallet level. That is acceptable to us, if it stays at the pallet level. Let's say goods come from Asia. A certain percentage of them are lost at the dock, in transit, in shipping, with the trucking and so on. They are damaged and can't be used. There's a fair amount of wastage to wholesalers and retailers. We've been told that the RFID would help to individually track each pallet. I also believe there are national security reasons for tracking pallets of goods because you don't know exactly what they contain. That is fine.
The problem is when you break the goods out of the pallets. Let's say there are shoes being sent from Brazil. Do you have an RFID in each shoe so you can account for theft, people walking into the store putting on new shoes and walking out? If so, the privacy implications are enormous. There is one unique identifier in every RFID that can emit your location to a reader. If there's not some way of either preventing the RFIDs going in at an item level or turning the RFID off at the point of purchase securely, you could track where people are going or link it up to the card they paid with.
