Abstract

This study outlines the creation of an RFID-based attendance tracking system using a NodeMCU ESP8266 microcontroller, MFRC522 RFID card module, and Google Sheets integration. The system streamlines attendance procedures by automating the process, offering a user-friendly solution suitable for educational and organizational environments. Utilizing RFID technology for identification and authentication, combined with the internet connectivity of the NodeMCU ESP8266, attendance data is uploaded to Google Sheets in real-time. Integration with Google Sheets facilitates efficient data management and accessibility for administrators and stakeholders. The system is built using affordable hardware components such as NodeMCU ESP8266, MFRC522 RFID card module, 5V buzzer, breadboard, and jumper wires, resulting in a compact and cost-effective attendance monitoring setup. The paper delves into the system architecture, hardware design, software implementation, and the integration process with Google Sheets. Experimental results validate the system's efficacy and reliability in accurately recording attendance data and simplifying administrative tasks.
