iphone 12 have fingerprint

True, but then you just enter your passcode when you have a mask on. We won't likely be wearing masks the rest of our lives however, so to me it's not an issue. iPhone 12 will run circles around an iPhone 7 these days.

Face ID only.

Thank you for the answer. Guess I'll be getting my iPhone 7 repaired then.

Certainly your choice. But Face ID is in my opinion, far superior to Touch ID.

And much more secure.

Indeed!

Not when you wear things on your face all day.

It will cost you $319 USD to repair your iPhone 7. You can by the iPhone SE 2020, which has Touch ID and the same internal parts as the iPhone 11, for $399.
