Very cool idea! I once worked on something similar [1], but even more low-tech, for CHI student design contest[2](we won). The idea was to do it over an IVR call and without a necessity of smartphones. The users were older people in India who find it hard to use and trust payments. I would love to work on this. I feel, we need more projects in offline and digitally accessible payments. On one end we have Apple Pay later and the other hand we have cash.
