The QR code feature, similar to Venmo’s QR codes and others, will allow a user to scan a friend’s code with their smartphone’s camera to send or request money, while the sharable payment links will let you publish your payment address outside of Facebook itself.
A Facebook spokesperson confirmed the feature’s launch, but characterized it as a “test” that’s currently taking place in the U.S. “To make payments on Messenger even easier, we’ve begun testing the ability for people to use QR codes and payment links when they want to send or request money,” the spokesperson said.
