I understand how actual payments are more secure with ApplePay. I'm wondering how the initial enrollment works. From the keynote, it seemed that you just take a picture of the card, and it's enrolled.
What's to stop me from taking a picture of someone else's card? Obviously the fraud can still be tracked to the phone initiating the charges, but there are lots of stolen phones out there. It's much easier to steal a phone than to print your own credit cards (especially chip cards). And your enrolled phone will now be considered to have gold-standard fraud controls.
Is there some process for the bank to confirm you intended to enroll a card?
There is probably a system where the card makes two small charges to your card and you log in and report the amounts. Apple said that enrollment required some sort of verification from the banks, but they didn't specify EXACTLY what that entails.
