This seems like a great idea and a perfect fit for bitcoin. It reminds me of early demonstrations of remote payments by sharing a bitcoin "invoice" qr code with a willing payer via livestream or just text. I think Roger Ver demoed that use case back in the early days. Since this 33me to involve payment via credit or debit card, I'm curious about how charge-backs are dealt with. I think in-person transactions generally are "insured" so to speak by the payer being present and maybe even on camera. It seems like the remote payer could potentially game a system like this because they are anonymous, off camera, and could just accept the bitcoin and then do a charge-back at some point afterwards. Maybe the protection is that their credit/debit card company would flag this sort of activity if it happened too frequently?
