Fuelled by coffee and collaboration—and almost no sleep—the participants tackled a life-saving brief: how to identify and assist millions of pilgrims swiftly & reliably. Mirza’s team proposed Hajj ID, A human-centred system of water-resistant NFC/QR smart wristbands, intuitive colour-coding, universal pictograms and a multilingual cloud database that integrates with Ministry dashboards. Praised for its affordability (under SAR 5 per pilgrim) and scalability, the prototype demonstrates how thoughtful design can enhance safety for the Guests of Allah while keeping operational costs low.

By lending her branding expertise to a record-breaking hackathon and receiving recognition from both Guinness World Records and the SFCPD, Samar Mirza exemplified the practical power of clear visual communication in large-scale humanitarian challenges.
