Attendance management plays a vital role in academic and organizational environments, yet traditional methods such as manual roll calls and signature sheets are inefficient, error-prone, and susceptible to manipulation. This research presents the design and implementation of a smart attendance system that integrates RFID technology with NodeMCU ESP8266 and Google Sheets for real-time data logging. The system employs RFID tags for identification, an ESP8266 microcontroller for processing and Wi-Fi connectivity, and Google Apps Script for cloud integration. A 16×2 LCD and buzzer provide immediate feedback to users. Experimental results demonstrate that the system records attendance within 2–3 seconds under stable network conditions, achieving 100% accuracy in data transmission. The proposed system is cost-effective, portable, and scalable, offering a practical solution for educational institutions and workplaces.
