The document discusses the advantages of an electronic attendance (E-Attendance) module over a manual system. E-Attendance allows teachers to record attendance anytime through SMS and automatically calculates totals. It also enables administrators to view attendance summaries and identify patterns of absenteeism. The system works by having students and staff scan ID cards upon arrival and departure. Hardware requirements include computers, ID card readers, and a controller box to manage the readers. Potential issues and their solutions are also addressed, such as unstable power supply, lost cards, and slow reader speeds. Cost estimates are provided for both software and hardware.
