The problem is lots of retailers don't even have the logo. You literally tap the phone to the terminal and it magically works. No indication whatsoever.
small businesses seem to be the quickest to adapt out here. Don't forget most of these businesses get terminals for free or little cost because they don't have to worry about a whole computerized POS system.Shops in the US commonly offer money if you sign up for a loyalty program/mailing list, but I don't think that is necessary at all for Apple Pay. Awareness is important of course, but I don't think people need an incentive to use Apple Pay, shops need an incentive to accept it.
Personally, I would use Apple Pay literally everywhere if I could. I hate carrying around numerous cards and look forward to the day that I can stop doing this, because currently they make my wallet too fat (I'm going to carry my phone around anyway, so it may as well serve more purposes). I hate carrying around cards so much that I will probably buy a $155 dollar Plastc to get rid of them, if it proves effective, even though I am pretty confident (and very much hope) that Apple Pay will be accepted everywhere within a couple years.
My main concern is that small retailers/restaurant/shops, where I make most of my purchases, will be slow to adopt. It's great that McDonald's accepts Apple Pay, but I never go there...
