This project focuses on developing an RFID-based attendance and counting system using an Arduino UNO and PIC16F877A microcontroller. The system employs an RFID reader to scan tags, automatically recording attendance and displaying real-time status on a 64-LED array and displays total number of students in the class, number of present student in class, number of  girl and boy presents in class and also roll number on 20*4 LCD module. The RFID reader scans RFID tags, which are uniquely assigned to individuals, and sends the data to the Arduino UNO. The microcontroller processes this information and logs attendance. A multiplexer is used to handle multiple RFID tags simultaneously and to manage the large number of LEDs (64) used for visual signaling, which can display the attendance status or alert conditions. The LCD display provides additional information such as the current count of attendees or any system messages, offering a user-friendly interface. The entire system is powered by a portable battery, making it suitable for mobile or remote applications without the need for constant power connections. This RFID-based system simplifies attendance recording and enhances accuracy while providing a scalable solution for various environments like classrooms, offices, or events.
