I agree with bmelton that one day I expect (hope?) NFC to replace QR codes. Beyond that, in terms of current alternative to QR codes, I'd have to say a short URL. It's not an exciting answer, but here's why I think that: 1) It can be memorable. The QR code requires a user to be at the location with a data connection. We've all seen people complain about/poke fun at QR codes in subways. But consider .com/14thStStop--much better, right? (Though you have to be careful or you come off like one of those late night infomercials.) 2) It's likely just as quick as QR codes. It's not "sexy" but I think it's more useful. And, at the very least, you can use it in conjunction with a QR code. Just throw it next to the code.
