This document describes an RFID-based school/college attendance system that uses RFID tags to track student attendance and notify parents via SMS. It uses an ARM7 microcontroller, RFID reader, GSM modem, and other hardware to read RFID tags, record attendance data, and send notifications. The system assigns each student a unique RFID tag. When a student scans their tag, the reader records the time and date and sends the student details to parents via text message. It also controls access to doors/lockers based on the attendance database.
