NFC terminals are growing at the same rate as NFC cards, but cards have a pretty long lifespan so my old debit card which is ~5 years old is still chip and pin, while my new credit card from the same bank is both chip+NFC.
I’m not going to go through the hassle (a few clicks) of replacing my card just to get NFC. The same goes for retailers, terminals get NFC on the next replacement.
