Chip+PIN is the basis of contactless+PIN, same EMV standard, same stuff happens under the covers. Different business rules for merchant risk, chargeback etc
That doesn't happen with Apple Pay though, since it's an authenticated NFC payment. My (physical) Visa card has a 50€ contactless limit but with Apple Pay, I can just use it to the card's limits. I've paid for a 880€ MacBook with just tapping my Apple Watch against a reader.
As far as the reader is concerned, for contactless, there is no, as in none as in nada difference between a contactless payment with a physical Visa card, or a contactless payment using Apple Pay (or Google or Samsung Pay).
They are all "authenticated NFC payments".
It doesn't change the fact that the reader doesn't know if it's a phone or not, it's just a contactless payment standard
So there aren't "different limits" for Apple/Google/Samsung Pay compared to using your physical Visa/MC/Amex/Discover/etc card.

Not from the _payment_ provider (mastercard/visa/etc), but from the _card_ provider (google pay/apple pay/banks) - e.g. my Bank card has a contactless limit of £100, but that same card via Google Pay has a limit of ??? (never reached it, thousands probably)
