I love how everyone here (most everyone at least) acts like Apply Pay just made cash money/credit/debit cards irrelevant which it hasn't and never will.
But if I can pay with credit why can't I pay with the credit card stored on my phone? What's the difference to the retailer if I swipe a piece of plastic or hold my phone to the POS terminal. Is the retailer getting more data about me and my purchase if I swipe vs using my phone? If so they should just be honest about it and say Pay doesn't provide them the data they need to provide the customer a better experience.
