Not only Wal-Mart - like eelf said WalMart brutalizes their vendors so getting into WalMart in and of itself is not that exciting.
RFID helps retailers streamline inventories and ordering. A click of a mouse will let retailers know what their on hand supply is at all times.
Vendors that don't build this capability into their products run the risk of retailers running out of their products - cuts into everyone's bottom line. Sorry if you already knew this, but it is rather exciting to me. Then again I am old so it dosen't take much anymore :)
