Following on from Bango’s agreement to provide payment services to Facebook in February, Facebook has announced the initial availability of these services to its developers as part of an improved mobile payments flow.
Facebook says here: “At Mobile World Congress this year we announced an improved mobile payments flow for mobile web apps. Today we are starting to roll it out. This low friction (two steps) carrier billing is now available on the majority of carriers in the US and the UK and will be rolled out to additional operators worldwide.”
There is a link to their Mobile World Congress presentation here.
If you are in the UK or US you can see this flow by visiting Facebook on your Android phone or iPhone at m.facebook.com and then (for example) using the Skyscraper City App.
