Or say you're in a restaurant with people with whom you're going Dutch, one can pay the whole bill and the others reimburse him on the spot with mobile pay.

In commercial situations it MIGHT be useful in cases where MobilePay is accepted but no cards (haven't seen such, though)

Of course some evil FT'ers came up with the idea of mining points by using this method.
