I'm curious about the security implications of this though. Seems like it would be easy to make a NFC sticker "skimmer" that you sticker over the official sticker.
It doesn’t scale due to limits.
And it doesn’t work as easily as credit cards as you will have to go trough the Apple Pay merchant KYC process for these to be billable which means you will have to verify your business.
Credit card skimming works because the stolen details can be used anywhere in the world and the cash is pretty much immediately transferred.
They can also be used to buy physical goods which can then be resold.
You can’t do the same with NFC tags.
If I skim your card in Chicago I can bill $2000 in a “coffee place” in Manila.
The same doesn’t work with NFC tags which not only can and likely will be geofenced but there’s no details to skim and the payment goes through Apple Pay not the credit card network which anyone can access.
I think the attack would be to place a sticker that causes unsuspecting users to pay you instead of the intended merchant.
Essentially as soon as somebody reports you to Apple your account will be burned.
Of course, it's up to Apple to implement and administrate it, they are generally pretty sensible about this kind of stuff.
But I agree this is nice. convenient.
