Rapid access to patient medical information is critical in emergency situations where timely clinical decisions can greatly affect the outcome of treatment. However, there is still a large portion of the population without readily accessible digital health records, and many of the solutions are internet-dependent and battery-powered, which limits their reliability in a critical situation. In this paper, a secure battery-free wearable and cloud-based framework for on-the-spot emergency medical information retrieval is presented. The proposed system combines a battery-free wearable device that is embedded with Near Field Communication (NFC) and Quick Response (QR) technologies to achieve fast and contactless access to encrypted patient information. A cross-platform mobile application written in the Dart language (Flutter) and a cloud backend (Firebase) for secure storage, authentication and real-time synchronization of medical records. The framework has the provision for both online and offline access to ensure the availability of crucial medical data even in low-connectivity environments. Encryption mechanisms are implemented to ensure the security of sensitive patient information and to ensure controlled access to that information. Experimental evaluation shows system is able to access critical medical data in seconds and helps to improve emergency response efficiency and digital healthcare accessibility in resource constrained environments.
