Working demo. This is a working demo of the live system. Everything works end to end in test mode: buy sets, get your QR codes, and redeem them on the Redeem tab. No real payment is taken yet. The live Ambeng Amal campaign, with real payments, launches at this same address soon.

The pain point
Charity meal coupons usually mean paper vouchers or screenshots that anyone can copy. The restaurant can't tell whether a coupon has already been used, and the charity can't see what's been sold or redeemed until long after.
Who it's for
Donors
Rumah Makan Minang counter staff
Darul Ihsan Orphanage (MTFA)
What it does
Buy sets online, get one single-use QR code per set by email, and give RMM counters a one-button scanner: green means serve, red means already used (with when and where). DIO sees every sale and every scan as it happens.
The story
Ambeng Amal, a fundraiser between MTFA's Darul Ihsan Orphanage and Rumah Makan Minang. A donor picks how many nasi ambeng sets to buy (each feeds 2–3), pays, and gets one QR code per set, so a set can be forwarded to family or friends. Staff at any RMM outlet scan with their phone's browser; there's no app to install. The first scan wins, even if two phones scan the same code at the same moment, and every scan is logged for the DIO dashboard. Vibe-coded with Claude Code in a day, on Vercel, Supabase, Resend and Omise (card and PayNow).
Walkthrough
From buying a set to the counter scan, and what happens if the same QR is scanned twice.
