Facebook is trying to make mobile transactions easier by rolling out a new mobile payments process for developers who want to use Facebook Credits to monetize their mobile web apps. This follows a promise the company made at this year's Mobile World Congress to address the sometimes complicated process of making transactions using Facebook Credits.

On the company's developer blog, Facebook said its new "low-friction" payment process reduces the number of steps required to purchase digital content from seven steps to only two, and allows customers to take advantage of direct carrier billing. Consumers can place their purchases directly onto their monthly mobile bills.

Supported carriers of the new payment flow in the U.S. include T-Mobile, Sprint and AT&T. Other carriers worldwide include O2, Vodafone and Orange. (A full list of supported carriers is available here.)

Facebook said that developers who have already intergrated Facebook Credits on their app don't need to do anything to use the new low-friction payment flow. New developers interested in using Facebook Credit's new payment process can visit the developer site.
