Imagine yourself at a party or a bar or perhaps at a meeting, now imagine you meet someone new there and become real-life friends with them. The next obvious logical step would be to add them over on Facebook to become friends in the online world, right? Well, if you and your new friend have an NFC-equipped smartphone and have a certain app installed, you can just tap the two together to become Facebook friends! No more of that awkward waiting period between you sending them a request and waiting for confirmation!
