This is something I find so fascinating about the American financial system... Home Depot in Canada has taken tap payments and Apple Pay for a long time now.
Yeah Home Depot is a bizarre exception, AFAIK they signed a contract with PayPal at some point long ago that prevents them from accepting tap-to-pay. Their checkouts have all the hardware for tap-to-pay, but contractually they can't turn it on.
Hopefully that contract ends soon, because wow did they shoot themselves in the foot on that one.
