A secure, real-time, and efficient employee attendance tracking system using RFID and dual-factor authentication (RFID + PIN). Developed as our final year engineering project at Higher School of Computer Science – Sidi Bel Abbès (ESI-SBA), this system is designed to modernize and simplify employee check-ins in workplaces using IoT technologies.
Traditional check-in systems are often manual, inefficient, and lack proper analytics. CheckMate solves these issues by combining hardware-based access control and a cloud-powered dashboard for real-time monitoring and management.
- Dual-factor authentication: RFID card + 4-digit PIN
- Real-time attendance updates with cloud synchronization
- Employee statistics dashboard (daily/monthly with PDF export)
- Admin panel for employee and RFID management
- Secure access control via servo motor + visual feedback (LEDs)
- Arduino Uno
- NodeMCU ESP8266
- RFID Reader RC522
- 4x4 Keypad
- Servo Motor
- LEDs
- Backend: Node.js (Express)
- Database: MongoDB
- Deployment: Vercel
- Communication: Serial (Arduino ↔ ESP8266)
I contributed primarily to the hardware and embedded systems, specifically:
- Wiring and integration of Arduino Uno + ESP8266
- Writing the complete Arduino code for RFID + keypad input + servo + LED handling
- Writing and debugging the ESP8266 code for Wi-Fi connection and API communication
- Real-time interaction between hardware and cloud
This project was developed by a team of 5 students at ESI-SBA (4th year, 2nd Cycle – Information Systems Engineering):
- [@Abderraouf Atsamnia] – Hardware design, Arduino & ESP8266 code, system integration
- [@Senouci Ibrahim] – Hardware design, Arduino & ESP8266 code, system integration
- [@Asmaa Baiche] – Frontend development, UI/UX
- [@Hallouche Abdessamed] – Frontend development, UI/UX
- [@Cherrak Ismail Anis] – Backend APIs, Database design, cloud deployment (MongoDB + Vercel)
Special thanks to our supervisor Mr. Rahmoun Abdellatif for his support and guidance throughout the project.
