Singapore Fintech Festival
One card. Both directions.
One credential lets a creator or micro-merchant accept a payment and get paid out on the same card they already carry.
Follow a live-streamer as she uses one credential to accept a payment, get paid, and spend it again, all while she's still live.
No checkout. No receipt. No record of the sale.

Hold the card she was paid on near the reader.
Illustrative — the same card, spending out.
