I was pretty pissed looking for an apartment in LA where every sign had a QR code for you to get the apartment info. I think by you doing this they suckered you into creating an account and/or paying for it. I have no idea how to scan a QR code. I think I searched once in the android store, downloaded an app and it didn't work. They're basically just glorified short urls which doesn't interest me (gratuitous use of technology much?). The cool application I see is to actually transfer real data, but not too many people do that.
