I'll personally support this claim, on my iPhone Apple Pay is so seamless (finger over home button and done) that I'll consciously want to purchase it more.
Similar story for one-click solutions such as paypal and amazon. If I don't have to get my card out then I'm far more likely to make a purchase.

One of the best use cases for touch id. Apple pay with FaceID is so much more of a pain in the rear. I have to double click the power button, position the phone so it can see my face, then put it back over the reader. Not at all seamless.
