Quick add when out and about ?

We should be able to have a quick add, so for example, if I was talking to another person or couple in a club or social and I wanted to add them on SwingHub, they should be able to have a QR code available in the phone wallet where I could scan with my camera, where I be taken directly to their profile. with a various options pop-up with i.e. wink remind me later to message maybe.
