As I mentioned in another comment:

I see QR codes everywhere too. But I never see them used , and nobody in my circle uses them. And the only times I hear about them is when people complain about them in Restaurants etc.

May very well be different in other locations (I'm in small town in Canada, just outside of Toronto, traveling to Ottawa frequently). I would guess without any evidence that downtown NY or Boston may see more use :).
