> show their QR code to vendors who scan it to charge their account.
That sounds _brilliant_ -- being able to show a physical QR code card rather than dig out the phone sounds like it would help a lot with preventing damage/loss of phones.
Yep, because everything is QR-based I can provide almost the same experience for people on their phones or those who opt for a card. The card even has a URL on it you can go to to claim the card (convert to a user account in the system) or a page you can go to and see the balance without needing to create an account.
