This document describes an IoT-based smart attendance system using RFID and Google Sheets. The proposed system uses RFID tags and readers to automatically record student attendance in real-time. It stores attendance data on a Google Sheet using a NodeMCU microcontroller connected to the RFID reader over WiFi. The system aims to make the attendance process more efficient, secure, and time-saving compared to traditional manual methods. It provides a prototype and discusses the hardware components, methodology, and potential applications of the smart attendance system.
