NFC in Health Monitoring : A New Era of Medical Cards and Application

The Efficient and safe patient data management remains a significant concern in modern healthcare, with current systems experiencing delays in information retrieval, security risks, and limited interoperability. These inefficiencies limit real-time decision-making, raise administrative costs, and compromise patient care. This research paper describes an NFC-based health monitoring system that combines NFC-enabled smart cards with a secure web application to provide real-time, encrypted, and role-based access to patient health records. By addressing data fragmentation and security threats, the suggested system improves patient-doctor communication, increases workflow efficiency, and strengthens data privacy using AES-256 encryption. The system, which was developed utilizing the System Development Life Cycle (SDLC) methodology, enables scalability, adaptability, and easy integration into hospital infrastructures. Performance assessments show a 98% data accuracy rate, a 95% user satisfaction rate, and an average reaction time of 50 milliseconds, outperforming typical RFID-based systems in efficiency, security, and dependability. The Proposed work suggested that NFC-enabled healthcare solutions provide a disruptive approach to digital health management, allowing for faster patient data retrieval, improved security, and seamless interoperability. It confirms NFC technology as a scalable and future-ready option for secure health information sharing, paving the way for new applications such as AI-driven diagnostics, IoT-based patient monitoring, and blockchain-secured medical records.
