Don't worry, Facebook isn't about to start charging a monthly fee to use it. That's a common hoax that's been debunked. Facebook will never charge you to use it; you're too valuable as a commodity! But that doesn't mean Facebook isn't looking for more ways to boost its bottom line.
A Stanford computer science student hacked into the code of Facebook's controversial Messenger app for iOS. He found clues that all but confirm Facebook is working on a way to use the app for mobile payments. It makes perfect sense, though.
Google's been trying to break into payments for a long time, and with the iPhone 6, Apple might have just succeeded. The tech giants see mobile payments as the future currency, replacing cash transactions once and for all, and all of them want to get in on the ground floor. That includes Facebook.
