This. I’d complain more about Face ID if Apple Pay wasn’t the first payment mechanism I’ve used that reliably fulfills the promise of being faster/easier than cash, and Face ID + mechanical button is a big part of that.
Still, Apple Pay was way more reliable with TouchID.
Step 1 : take the phone off your pocket
Step 2 : put it against the terminal while touching (not pressing) the home button.
Step 3 : there is no step 3, you already paid because even if the phone wasn’t unlocked the NFC reader automatically unlocked it, opened your default card and validated the payment thanks to your finger being on the reader.
Compared to FaceID, no need to double press a button and to watch your screen waiting for the little animation to finish.
Don’t get me wrong, paying with FaceID totally works and it’s fast. But paying with TouchID wasn’t fast, it was instant and thoughtless.
