Mobile payments for me have always had a better conversion with paypal for the very reason he states. With the Paypal API you can pull the users full name, email, delivery address, and create an account on your site for returning customers (send them an activation and request password etc) or building a mailing list or whatever else.
I wonder why they got no mastercard/visa verification thing, most sites where you pay with a card ask for verified by visa and mastercode or whatever they are called. Their flow just got messy.
