A Comprehensive Review of RFID-Based Smart Library Management Systems Using IoT and ESP32

The Internet of Things (IoT) technologies have evolved at a very high rate, replacing the traditional library management systems with smart, automatic, and efficient management systems. Among these, RFID-integrated library systems have come out as an effective solution in the automation of issuing and returning library books and controlling their location and use of their hardware by the users. The paper is a critical overview of RFID-based library management systems merged with IoT systems based on ESP32, ESP8266, and Arduino microcontrollers. The research examines different systems that integrate RFID technology within wireless communication system such as Wi-Fi, cloud systems, and mobile apps, for real-time data synchronization and links. Also, recent research work is analyzed to be able to see the major tendencies in automating, tracking in real-time, intelligent security, and the implementation of advanced technologies, including machine learning and robotics. The benefits of increased efficiency, low human input, higher accuracy, and user experience are clarified, whereas such weaknesses as security vulnerability, network reliance, the expensive cost of implementation, and the complexity of the system are examined critically. Also, the comparative analysis of the existing systems requires that scalable, secure and intelligent solutions are needed. The potential future developments, such as the automation of systems based on artificial intelligence, edge computing, and security utilizing blockchain methods, are also discussed to improve the performance and reliability of the system. The results of this survey have great value in explanation to researchers and developers of tomorrow working on structuring and furnishing next-generation smart library systems as bespoke, safeguarded and scalable structures
