Facebook is testing a way to make paying with a credit card easier, but it works with PayPal, not against it. The feature pre-fills credit card and billing info for making easier purchases through PayPal, Stripe, Braintree or other payment processors in third-party mobile apps.
Let’s say you click through an ad on Facebook to an e-commerce app or visit an e-commerce app on your own. When you go to make a purchase you’d normally have to type in your credit card and billing address information on your tiny keyboard. That’s a hassle that discourages people from actually buying things.
With Facebook’s new payments test, you’d see a button that says something like “Let Facebook Input My Billing Info.” You’d then see a data permission request asking you to allow access to the billing info you’ve previously stored with Facebook from buying Gifts or making payments in games. With one click, your permission fills in all that billing info and you can hit the “Confirm Purchase” button.
