Facebook has moved to simplify the way developers charge for their mobile Web apps with the launch of a direct-to-carrier billing system.
The new process, outlined on Facebook's developer blog, requires users to take just two steps to make a payment - compared to seven, including SMS verification, for the old system.
Users who want to pay for a virtual or digital good in a mobile Web app just open the payment dialog and confirm their purchase.
The new system comes after the social network inked a deal with UK-based mobile billing and analytics firm Bango.
Initially unveiled at Mobile World Congress in February, the service has now gone live with US and UK giants including AT&T, Sprint, Vodafone and O2, with operators in more than 60 countries set to follow.
Facebook is keen to find ways to make money from the increasingly important mobile arena, admitting in filings ahead of its recent IPO that the shift to handsets is hitting advertising revenue.
