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. Two examples are given: first, a case where a QR code is used to easily scan a person's contact info from a business card into a mobile device. 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.
