If they'd launch it, Apple Pay is FAR more useful in the UK than in the US. In the UK, contactless payments (like Apple Pay) are fairly widely accepted, while they are rare in the US.
I do agree. I want apple pay now, because I've usually got my iPhone in my hand in the queue anyway. Certainly more easily accessible than a card in a slot in a clicked-shut wallet in a pocket. Even more so driving and using a drive-thru, because my iPhone is out on the dash somewhere.
The Plastc just covers everything for me. It would replace about 6-7 cards (payment cards and other types) for me.
