I don't understand - do you pay for everyday goods and services with wire transfers and direct debits? Because that's the use case of Apple Pay isn't it?
I'm not sure how anything could be quicker than a credit card. A normal contactless transaction from me taking my wallet out of my pocket to being done takes about two seconds. Apple Pay is no different except I take my phone out of my pocket instead of my wallet. Maybe Apple Pay by watch could be quicker?
