I appreciate your advice and as I mentioned I am all for QR codes.

But, first and foremost, I am for IT security. So informing everyone of the potential is of utmost importance. Email and website links are similar in many respects and as user awareness improved, damages decreased.

QR codes are a bit more benign, they do not require electronics. So, they're going to be everywhere in short order. If a "proof of concept" helps people become more aware of what's possible, that's a good thing.
