Don't know the company that's doing that. Just know that Walmart's getting ready for "2005 Sunrise". I know, stupid name. But that's where all US stores must be able to scan UPC and EAN codes. Right now they can only scan UPC's. I've got a couple friends in the IT dept there. I'll send them and e-mail and see if they know. They've also got the RFID project going. That's a big mess.
Walmart Supplier Commitment: Walmart and the United States Department of Defense (US DOD) mandate their vendors to use RFID technology by 2005. The Walmart RFID technology strategy is to leverage EPC and ISO compliant RFID standards. "Keep it simple" is the message Linda Dillman (WalMart CIO) delivered to technology vendors at the Walmart RFID Technology session.
