College GateKeeper is an innovative security management application designed to streamline and enhance the monitoring of student attendance and security within educational institutions. This project empowers college security guards with a comprehensive toolset to manage access and track student movements effectively. Key Features: • Secure Authentication: College GateKeeper ensures a secure environment with individual login credentials for each security guard. Additionally, a master password adds an extra layer of authentication to validate access requests. • ID Card Image Capture: Security guards can effortlessly capture students' ID card images using the app. This feature facilitates quick and accurate identification of students within the college premises. • Roll Number Retrieval: Upon capturing the ID card image, the app fetches the scanned roll number from the server. Guards have the option to confirm the information or retake the image for accuracy. • Attendance Logging: The application seamlessly records the out time when a student leaves the college premises. This information is securely stored in the database, providing a reliable record of student movements. • In-Time Recording: When students return to the college, their ID cards are scanned again to log their in-time. This ensures a comprehensive attendance tracking system for accurate reporting. • Defaulter's List: College GateKeeper automatically identifies students whose in-time exceeds the permitted limit. Details of such students are promptly added to the defaulter's list, facilitating the imposition of fines as necessary. Overall, College GateKeeper not only enhances the efficiency of security operations but also contributes to maintaining discipline by enforcing attendance policies. Implementing this project demonstrates a commitment to leveraging technology for a secure and organized educational environment.
