CONTACTLESS INTELLIGENCE: RFID-BASED LIBRARY AUTOMATION USING AT89S52

Abstract

The rapid growth of information resources in academic and public libraries has necessitated efficient and reliable automation systems to replace traditional manual processes. This study presents an RFID-based library automation system powered by the AT89S52 microcontroller, designed to streamline book issuing, returning, and catalog management. Radio Frequency Identification (RFID) technology offers a contactless and secure mechanism for book identification, thereby reducing human intervention and minimizing errors associated with conventional barcode-based systems. The AT89S52 microcontroller serves as the core processing unit, controlling RFID readers, managing data communication with the central database, and ensuring seamless execution of transactions. By integrating RFID tags into library books, the system enables rapid identification and prevents duplication or theft. The proposed solution enhances user convenience through faster check-in and check-out procedures, while also assisting administrators with automated record maintenance. Experimental validation demonstrates that the system provides higher accuracy, improved efficiency, and scalability, making it a cost-effective and robust alternative to traditional library management methods.
