> even add a tip or sign for some purchases? Why would anyone want to sign on a phone? Why would anyone want to sign for a credit card purchase at all? Consider this the obligatory comment of "why do Americans want to sign for credit card purchases when PIN is so much better?". I don't even think I have a signature on my card. I haven't even swiped or inserted my card in months, everything is contactless with my card, I'm concerned I'll forget my PIN.
