RFID-Based Attendance Management System Using ESP32 and Google Sheets

Abstract

This paper introduces the development and design of an RFID-Based Attendance Management System Using ESP32 and Google Sheets to improve accuracy and efficiency in taking attendance at educational institutions. Conventional attendance mechanisms, including paper records and manual roll calls, are inefficient, prone to errors, and vulnerable to fraud. To counter these factors, this system utilizes RFID technology to mechanize attendance marking and provide a smooth, secure, and real-time solution. The system comprises RFID readers and tags, with an ESP32 microcontroller that handles attendance data and uploads it to Google Sheets for cloud storage and management. This integration provides real-time monitoring, convenient access, and improved organization of data for faculty and administrators. The automated system saves the manual work, minimizes human errors, and ends proxy attendance, thus being a more scalable and reliable option compared to traditional methods. Meant to be affordable, portable, and easy to use, this smart attendance system is tailored for academic institutes as well as commercial businesses. Having used cloud-based management, it promises effective record-keeping, secure data storage, and improved accessibility, thereby overall enhancing attendance tracking and institutional productivity.
