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.
The difference between genius and stupidity is genius has its limitations, stupidity doesn't.
