Introduction
Managing attendance in schools, colleges, and offices is often time-consuming and prone to errors. To overcome this, we can build a Smart Attendance System using RFID (Radio Frequency Identification) and Raspberry Pi.
This project allows students or employees to mark their attendance by simply scanning their RFID card. The data is stored automatically in an Excel sheet along with the date and lecture/session details. An LCD display and buzzer provide real-time feedback, while an admin menu allows enrolling and deleting cards.
This project is a low-cost and reliable solution for automating attendance management.
Working of the Project
- System Initialization
- Raspberry Pi initializes RFID reader, I2C LCD, and buzzer.
- Database (
rfid_database.json) is loaded. If empty, system starts fresh. - Excel file (
attendance_excel.xls) is created if not already present.
- Menu Options
On startup, the system shows 3 options:- Start Attendance System
- Enroll New Cards
- Delete Existing Cards
- Enrollment Mode
- Admin scans a new RFID card.
- If card is already registered → LCD shows “Already Registered”.
- If card is new → system asks for a name, saves it in database, and confirms with buzzer & LCD.
- Enrollment continues for multiple cards until admin types
"exit".
- Delete Mode
- Admin enters card ID to delete.
- If found, card is removed from the database.
- If not found, LCD shows “Card Not Found”.
- Multiple deletions possible until
"exit".
- Attendance Mode
- System asks for lecture/session name.
- A new Excel sheet (with date and lecture name) is created.
- Students scan their RFID cards:
- If registered → LCD shows “Welcome [Name]”, attendance marked as “Present” in Excel.
- If already marked → LCD shows “Attendance Already Taken”.
- If not registered → LCD shows “Register First”.
