This article makes me realize I probably have a misunderstanding about Tap to Pay -- so help educate me 
So, I always thought that if a vendor accepts contactless payment (e.g., a credit card or debit card in which you just tap using the built-in NFC chip) that it also means they would be able to accept Tap to Pay from iPhone that have NFC and the Apple Watch. So that's not the case?
My mental model always was that the iPhone NFC chip is simple an equivalent version of the NFC chip in the credit card.
Inform me!
UPDATE: Ok, I think I'm even more misinformed than I thought. Hahah. So in reading that Apple announcement, it looks like Tap to Pay is using one's iPhone to accept payments? Is that right? If so, that is indeed not what I was thinking about.
