It worked wherever those card readers with the wifi icon were. Those are still rare and with the advent of the new chip readers I think they'll get rarer yet.
Actually, I think it'll be the opposite. While new readers may not externally indicate they have NFC capability they actually do. As I indicated before, my local grocery store had replaced their card readers last summer or fall, there was ZERO indication that the new readers supported NFC. Last week they enabled mobile payments and now the screen displays the icon for tap and pay. Oddly, they have yet to start accepting the chip cards.
