You don't need reception of any kind to do an NFC payment, as long as the terminal has network access (even through ethernet).
the Prime code thing is a good point tho

I am surprised nobody has mentioned the real joy of checkout at Whole Foods, which is that there is no annoying, incessant voice asking every self-checkout shopper, "Have you scanned your rewards card yet?" and "Please complete the transaction on the pin pad." It must be sheer torture working all day with those going off constantly.
But... while all payment terminals are compatible to VAS and SmartTap, very few have the firmware and a POS that can make sense of it. So, in practice, beside Walgreens and maybe CSV, it is not much adopted.
