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)
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.
