Tapping the phone is not much faster than tapping my credit card.
"Tapping" a card is not a thing here in the US. Some banks supported the contactless cards early on (Mastercard might have been a "champion" of that at the time with MasterPass I think) but those cards have all but disappeared. Now it's either swipe or chip here in the US. I had one of those cards with the tap chip in it, never used it and the card provider no longer sends those out.
