The smart book borrowing and returning machine adopts a modern design, equipped with a high-definition smart interactive interface that intuitively displays functional modules such as borrowing, returning, and inquiry. The device integrates RFID multi-tag recognition technology, enabling rapid batch processing of book borrowing and returning operations, and significantly enhancing readers’ inquiry efficiency and inter-library borrowing and returning service capabilities. Its aluminum alloy ultra-thin body balances rust-proof and corrosion-resistant properties with optimized space utilization. Supporting reservation-based borrowing and identity verification functions, it effectively reduces queuing time and streamlines the borrowing process, assisting libraries in establishing an efficient, intelligent, and modern service system.
