📚 RFID-Based Library Management System (C++)

🚀 Overview

This project is a Library Management System developed in C++ with RFID (Arduino integration). It allows efficient management of books and student records using RFID technology.

The system supports:

• Book issuing and returning
• Student record management
• Fine calculation system
• Admin and employee role handling

---

⚙️ Features

👨‍💼 Admin Panel

• Add new books using RFID
• Add student UID (RFID)
• Delete books and student records
• View book allotment details
• View fine records
• Create admin and employee accounts

👨‍🔧 Employee Panel

• Issue books via RFID scanning
• Return books with automatic fine calculation
• Accept and update fine payments

---

🧠 Concepts Used

• Object-Oriented Programming (OOP)
• File Handling (Persistent Storage)
• String Parsing (stringstream)
• Serial Communication (Arduino RFID)
• Time Handling (Fine Calculation)
• Windows API (COM Port Communication)

---

🔌 Hardware Requirements

• Arduino Board
• RFID Module (e.g., RC522)
• RFID Cards/Tags

---

💻 Software Requirements

• C++ Compiler (CodeBlocks, Dev C++, Visual Studio)
• Windows OS (Required for windows.h)
• Arduino IDE

📂 File Structure

book.txt              → Stores book records
uid.txt               → Stores student data
fine.txt              → Stores fine records
*_admin.txt           → Admin credentials
*_employee.txt        → Employee credentials
<UID>uid.txt          → Individual user records
<BOOKID>.txt          → Book issue tracking

🔄 System Workflow

📌 Book Issue

1. Scan student RFID
2. Validate UID
3. Scan book RFID
4. Check availability
5. Assign book and update records

📌 Book Return

1. Scan student RFID
2. Scan book RFID
3. Calculate number of days
4. Apply fine if needed
5. Update records

---

💰 Fine Policy

• First 3 days → No fine
• After 3 days → Rs. 50 per day

---

🛠️ Setup Instructions

1. Connect Arduino with RFID module
2. Upload RFID reading code to Arduino
3. Connect Arduino to PC
4. Run the C++ program
5. Enter COM port (e.g., COM3)

---

⚠️ Limitations

• Works only on Windows (windows.h)
• Uses file-based storage (no database)
• No password encryption

---

🔥 Future Improvements

• Add GUI (Qt / Web / C#)
• Replace file system with SQL database
• Implement password hashing
• Add real-time dashboard
• Cloud integration
