Messenger, the ubiquitous instant messaging services included Facebook, introduced in the United States an option to raise money with your friends in a group chat (if they use the mobile apps for Android or iOS).
Until now it was possible to send money (or return the advance of a dinner, for example) only within a two-party conversation. But now group members can pay for a dinner, or a group gift, or whatever the reason you are collecting a fee from your friends. And even more: you can know who has actually paid his dues or not, but keep in mind that the deposit may not be immediate.
To the best of our knowledge, this feature only works in the US at the moment. It’s a useful option that should be available in every market because we don’t want to hear no more «Who’s not paid for John’s gift yet?» :)
