Functional requirements of RFID Based Attendance System with non-functional

Functional Requirements for an RFID-Based Attendance System

1. User Authentication and Authorization:
   • User Registration: Enroll users by capturing their RFID tags and associating them with their profiles.
   • Role-Based Access: Manage permissions for different roles (e.g., employees, administrators).
2. RFID Tag Management:
   • Tag Assignment: Assign unique RFID tags to users and link them to their profiles.
   • Tag Updates: Update or reassign tags as necessary (e.g., lost tags).
3. Attendance Tracking:
   • Check-In/Check-Out: Record attendance when users scan their RFID tags at designated checkpoints (e.g., entry/exit points).
   • Real-Time Processing: Process and record attendance data in real-time.
4. Attendance Reporting:
   • Daily/Weekly/Monthly Reports: Generate reports on attendance patterns, including check-ins, check-outs, and absences.
   • Custom Reports: Create ad-hoc reports based on user-defined criteria (e.g., specific dates, departments).
5. Alerts and Notifications:
   • Attendance Alerts: Notify administrators of unusual attendance patterns (e.g., missed check-ins).
   • Reminder Notifications: Send reminders for upcoming shifts or important attendance-related events.
6. User Management:
   • Profile Management: Create, update, and manage user profiles, including personal details and RFID tag information.
   • User Lookup: Search for users based on various criteria (e.g., name, ID, department).
7. Integration with HR Systems:
   • Data Synchronization: Integrate with existing HR systems to synchronize attendance data with payroll and leave management.
   • Automatic Updates: Update employee records and attendance status automatically.
8. Data Security and Privacy:
   • Access Control: Restrict access to attendance data based on user roles and permissions.
   • Data Encryption: Encrypt attendance data to protect user privacy.
9. System Configuration and Administration:
   • Settings Management: Configure system settings such as attendance thresholds, working hours, and access points.
   • Admin Dashboard: Provide an interface for administrators to manage and monitor the system.
10. Backup and Recovery:
    • Data Backup: Regularly back up attendance data to prevent loss.
    • Recovery Procedures: Implement procedures to restore data in case of system failure or data corruption.
11. Audit Trail:
    • Logging: Maintain a log of system activities, including user interactions, tag scans, and administrative actions.
    • Audit Reports: Generate audit reports to review system usage and identify potential issues.
