View the live demoTHE PROBLEM
In an accident, the people who reach you first — bystanders, paramedics — have no way to know your blood group, your allergies, the medication you're on, or who to call. The information that could change the outcome is locked inside a phone they can't open.
WHAT WE BUILT
A QR you carry — on a card, a sticker, a keychain. Scanning it opens a clean, mobile-first page with exactly what a first responder needs: emergency contacts, blood group, allergies, conditions, medication. No app to install, nothing to unlock. A person registers, fills their profile, pays once, and a unique QR is minted to them.
THE STACK
Shipped as a PWA — installable, offline-tolerant, no app-store gatekeeping. Next.js and Supabase for the app and data, Razorpay for payments, MSG91 for phone verification. Designed, built, and iterated by one person on an AI-driven workflow.
OUTCOME
A production-ready prototype, delivered and live for the client to test — including an admin dashboard, a bulk-issue flow for pre-printed QRs, and a claim flow for handing them out. Public go-live rests on the client's own steps (branding, telecom and KYC approvals). The working demo is linked above.
