Automated Attendance System Using RFID: Computer Engineering Guide
1. Introduction
Overview of the project.
Objectives of the system: Develop an automated attendance system using RFID technology to streamline the attendance process.
Scope of the system: Applicable for educational institutions, workplaces, and events to improve efficiency and accuracy.
2. Requirements Analysis
Functional Requirements:
· - Record attendance automatically when an RFID card is scanned.
· - Maintain a database of attendance logs for each individual.
· - Provide a dashboard for attendance management and reporting.
· - Generate alerts for unregistered RFID cards.
Non-Functional Requirements:
· - High reliability in scanning RFID cards.
· - Secure storage of attendance data.
· - Scalable to accommodate a large number of users.
3. System Design
Architecture:
· - Client-server model with RFID readers as clients and a backend server for data processing.
· - Integration with a web or mobile app for administration.
Data Flow Diagrams (DFDs):
· - Level 0: Overview of data flow from RFID card scanning to attendance logging.
· - Level 1: Detailed processes for data validation, logging, and reporting.
Database Design:
· - Tables: Users, RFID Cards, Attendance Logs, Alerts.
4. Technology Stack
Hardware:
· - RFID readers and RFID cards for attendance recording.
Frontend:
· - Web or mobile app for admin access using React.js, Angular, or Flutter.
Backend:
· - Python (Flask/Django) or Node.js for API development.
· - Integration with RFID reader software libraries.
Database:
· - SQL (PostgreSQL, MySQL) or NoSQL (MongoDB, Firebase).
Cloud Services:
· - AWS, Google Cloud, or Azure for hosting and data storage.
5. Implementation
