Sure, there are plenty of actual uses for RFID, what I meant is that most of the 'that'd be cool to play with' uses are impossible, and what is possible aren't the things you'd play with (I mean I don't have a warehouse, and for tracking stuff in my pantry it's impractical because of the reasons I mentioned earlier).

So does just about every other large supply chain. There's lots of practical use cases for RFID, they're just all pretty boring.
