Now... I could imagine a use for this tech for auth. With a mobile device, you could
create a soft token - where the qr code changes frequently - like with a securid. Maybe
even as part of a challenge response scheme - where the challenge is displayed to the
mobile device as a qr code and the device displays the response as a qr code. I am unaware
of anything existing that does this. But I certainly wouldn't see a static printed qr
code as useful for AuthN in just about any scenario.

Let me guess: somebody has decided that you *will* use this technology
whether it's appropriate or not, right? To answer your question, it's
possible but very unlikely because it's not a good way to do authentication.
