Facebook is now getting into the whole peer-to-peer payment trend. They will now let you send money to friends via Facebook Messenger. All you have to do is sync a credit card with your account.

This isn't new, but because of their sheer size, they could get ahead of this game.

Facebook did add extra safety for Messenger payments: A user PIN or Touch ID, if the user is on an iPhone. No payment can be sent without that PIN, which the user will create when they set up their account (or with the thumbprint scan). Users could opt out of this feature if they want to, but will be prompted to create one at registration, Davis says.

The transactions will be free, like Venmo and Google Wallet.
