Well unlike this author I am not ready yet to say I was wrong about QR codes, but I like the argument presented here and should pass it along.

Second, a case where QR codes are used to order food from a virtual store while waiting for a train. Also, here's a post from Library Girl on more educational uses of QR codes.
