Scan2Save: A QR Code-Based Digital Emergency Medical Information System for Enhanced Patient Safety

In medical emergencies, the lack of instant access to a patient’s health history creates a serious risk, commonly resulting in treatment delays or negative outcomes. Traditional approaches such as engraved jewelry or wallet cards are grossly restrictive regarding the quantity and adaptability of information conveyed. This article presents Scan2Save, a contemporary, web- based electronic emergency medical ID system capable of filling this critical information gap. The system leverages QR code technology to give first responders and medical staff immediate, secure access to a patient’s critical health information through any smartphone. The platform includes a secure user registration and profile management system, dynamic generation of QR codes, a dedicated emergency access portal with capabilities such as one-tap calling and voice alerts, and user-driven controls for privacy. Based on a scalable design with a React/TypeScript frontend and a Node.js backend, the system provides a holistic, globally accessible, and timely solution to enhance emergency response outcome and maximize patient safety.
