It looks like Facebook is working on a bunch of new features for its Messenger app, including the ability to pay for things in-store right through the app.
While Messenger already lets you send money to friends, source code dug up by The Information shows evidence of a new mobile payment feature that can authorize credit card transactions in retail stores.
Details of how the feature will work remains a mystery for now. Facebook could be planning to partner with already established mobile payment solutions, like Apple Pay, Android Pay, Samsung Pay and others, or set up its own system.
