This document proposes developing an active RFID-based automated attendance monitoring system for office management. Active RFID tags would be given to each employee and read by sensors at the office entrance to automatically record entry and exit times without manual sign-ins. The system could generate monthly reports on employee work hours, absences, and salaries to help with human resources planning and management. Key features include simultaneously reading multiple tags, and adjusting the reading range from a few meters to up to 50 meters depending on needs.
