IoT-Based RFID Attendance System – Arduino & Google App Script Code

IoT-Based RFID Attendance System – Arduino & Google App Script Code

The IoT-Based RFID Attendance System is an advanced cloud-integrated automation project designed for accurate and efficient attendance tracking.
It combines the power of NodeMCU ESP8266 with Google App Script and Google Sheets to create a real-time, online attendance management system.

How the Project Works

When a user presents their RFID tag to the reader, the NodeMCU ESP8266 reads the stored data — including Student ID, Name, and Class.
This data, along with the current time and date, is sent through Wi-Fi to a Google App Script Web App hosted online.

The App Script processes the data and automatically logs each record into a connected Google Sheet, creating a cloud-based attendance record that can be accessed anytime, anywhere.
Meanwhile, the local hardware provides instant feedback with a buzzer sound and displays a confirmation message on the LCD screen (e.g., “Welcome [Name]”), confirming successful attendance marking.

Project Features

• Automatic RFID-based attendance logging with real-time timestamp.
• Data stored securely in Google Sheets via Google App Script.
• Built with NodeMCU ESP8266 for IoT-based data transfer.
• Instant local confirmation with buzzer and LCD display.
• Eliminates manual entry, ensuring accuracy and speed.
