Smart Library Book Tracking with RFID & Analytics

Problem statement

Libraries struggle with tracking borrowed/returned books, preventing theft, and understanding real book usage. Manual systems are slow and prone to errors. RFID can automate the entire process efficiently.

Abstract

This project uses RFID tags on books and RFID readers at entry/exit gates to track book movement automatically. A central system logs borrowing, returning and unauthorized removal attempts. The dashboard displays real-time inventory, most-read books, category-wise analytics and overdue notifications.

Components required

• RFID tags (one per book)
• RFID reader (RC522 or long-range reader)
• ESP32 / Arduino Mega
• Database (Firebase / SQL)
• Library dashboard web app

Working

Books are tagged with RFID. When a book is borrowed, the reader scans it and updates the database. At exit gates, RFID readers detect unauthorized removals and trigger alarms. The dashboard shows book counts, borrowing frequency and overdue details.

Applications

• Libraries
• University book management
• Bookstore inventory automation
