Description

Abstract: The use of technology in educational institutions has grown significantly, improving efficiency in attendance tracking and overall administration. This project presents a NodeMCU based RFID card-based attendance system designed to automate real-time student attendance. The system uses an RFID reader to identify student-issued RFID cards, a NodeMCU microcontroller for processing, and an I2C LCD for immediate feedback. Each student is assigned a unique RFID card, which they tap on the RFID reader to mark their presence. If the system recognises the card, it displays "Present: 1" or "Present: 2" depending on the student's ID number. In the case of an unregistered card, the system displays "Wrong Card!" on the LCD. The proposed system ensures accuracy, reduces manual intervention, and prevents attendance manipulation, making it ideal for schools, colleges, and other educational settings. The integration of IoT technologies like NodeMCU enables real-time monitoring and potential expansion into cloud-based systems for remote management. This low-cost, efficient system has practical applications for streamlining attendance records, minimising errors, and ensuring transparency. With the scalability to accommodate more students or features, this project provides a Reliable Solution for Modern Educational Institutions.
