This research presents a new way to enhance smart home security by combining automated circuit control and NFC technology. A PN532 Reader Writer and a Raspberry Pi are used in the system's construction to control a servo motor for door access. Authentication uses symmetric encryption techniques to protect sensitive data by matching encrypted passwords saved on NFC tags with secure credentials controlled on a Flask server. In-depth evaluation confirmed the correctness and dependability of the system by showing a 100% success rate in correctly detecting and authorizing NFC cards. Rapid credential resets are facilitated by the system to mitigate any security threats such as theft or unauthorized access, guaranteeing ongoing protection. The system is further improved by an associated Android application that lets users keep an eye on access logs, add new users, and get real-time alerts when an unlock event occurs. This mobile interface improves user experience by facilitating smooth control over access management. The method provides a simple, effective way to regulate access while also strengthening the physical security of smart homes by combining NFC technology with cutting-edge encryption methods. By addressing major issues with automated, secure access systems, this study offers a workable and expandable solution for contemporary smart homes that advances IoT-based security while safeguarding data security, accessibility, and dependability.
