Abstract

Libraries require reliable ways to identify borrowers and maintain accurate circulation records. Manual issue and return procedures can take time and may lead to recording errors. This paper presents the design of a low-cost prototype for a smart library management system using an ESP32 microcontroller and an MFRC522 RFID reader. A registered student RFID card is scanned first to identify the borrower, followed by the RFID tag attached to a library book. The ESP32 processes the scanned identifiers and checks the corresponding borrower and book records before an issue or return operation is accepted. The prototype is intended to demonstrate a simple RFID-based circulation workflow using commonly available components. This paper describes the proposed architecture, hardware, software, operating sequence, and functional tests of the prototype. At a read distance of 2 cm, 9 of 10 scans were recognised and the average response time was 0.94 s.

Keywords
