Yes, but only "newer" ones. So larger chains you see them, but mom and pops will take a bit longer. Depends on when they got their merchant account/hardware. My point was that it's more common than you think, and it's used outside of tech circles.
Contactless MasterCard was deployed sporadically in the US 15 years ago. Few stores had the readers and few banks issued the cards so it died due to lack of demand. It is questionable that Apple will carry enough influence to better that track record.
