chips don't wear off

The chips may not, but the contact surfaces corrode. Then, when you're facing a slightly aged payment terminal with also corroded contacts, your card gets rejected no matter what you do.

So from my view, NFC in phone has two things going for it: it can be toggled on and off, effectively preventing drive-by cardjacking; and it is better protected from elements.

The fact that I have other personal reservations about contactless payments is different matter altogether.

Pencil erasers do a great job to clean these type of contacts :)
