Cost Effective IoT- RFID Attendance Database Management System using ESP8266

Attendance tracking remains an essential yet often cumbersome task for educational institutions and organizations. Conventional methods consume substantial time and effort. In this paper, we endeavor these limitations with an innovative and cost-effective solution. An Internet of Things (IoT) based attendance management system that harnesses the power of Radio Frequency Identification (RFID) technology. At the core of this system lies the ESP8266, a widely available and inexpensive Wi-Fi-enabled microcontroller. By seamlessly integrating an RFID reader with the ESP8266 and a database, the system automates the attendance recording process. Students or employees need to only tap their RFID cards or tags, and their attendance data is instantly and accurately captured, eliminating the potential for manual errors. The solution's significance lies in its multifaceted advantages, including automated attendance tracking, real-time data accessibility, and cost-effectiveness facilitated by the use of affordable hardware components. Future research may explore additional features, scalability options, and integration with other IoT systems to augment its capabilities further, this innovative IoT-RFID attendance system represents a significant stride towards modernizing attendance management practices while delivering cost-effective and reliable solutions.
