Arduino Uno R4 Wi-Fi Based RFID Attendance System

An Arduino Uno R4 Wi-Fi-powered intelligent, automated RFID attendance system that tracks attendance, timing and summary in real-time!

Despite being a vital component of everyday operations in workplaces, schools, and universities, attendance tracking is frequently tedious and subject to human mistake. With automation and real-time data logging, the Arduino UNO R4 Wi-Fi Based RFID Attendance System provides a sophisticated solution.

This technique makes tracking attendance easier by utilizing RFID (Radio Frequency Identification) technology. Every student receives and RFID card, which the system stamps as “Present – On Time” if it is scanned within the first ten minutes of powering up. Students who do not scan are immediately marked absent, while those who scan after ten minutes have their status changed to “Present – Late.”

Additionally, the system has a teacher’s master card that, when scanned, shows the attendance summary for every student who has enrolled on a 20×4 I2C LCD screen.

This project combines automation and electronics to provide a practical smart attendance solution that is perfect for:

1. Automated attendance without manual roll calls in schools and universities

1. Training Programs and Workshops: Simple Ways to Monitor Employee Presence

1. RFID-enabled rapid check-ins for seminars and events

1. Future enhancements could include syncing with cloud databases, enabling online data logging to Google Sheets and other platforms or integrating Wi-Fi access with the Arduino Uno R4 Wi-Fi built-in module.
