The document describes using RFID technology to develop an active student attendance system for kindergartens that sends messages to parents' phones informing them when their children safely arrive at and leave school. It also aims to reduce traffic congestion when parents pick up their children after school. RFID tags would be attached to student IDs and parent vehicles. Readers at school entrances would track attendance and trigger messages. Vehicle tags would allow notifying parents inside of child pickup to ease congestion.
