In today's era of rapid information technology development, libraries-as key hubs for knowledge dissemination-are undergoing profound transformations in their service models. Under traditional barcode systems, the borrowing and returning process presents clear bottlenecks: readers must locate each book's barcode, align it with a scanner, and process items one by one. This is not only time-consuming and labor-intensive but also prone to errors due to worn barcodes or improper scanning angles. The introduction of RFID (Radio Frequency Identification) technology has brought a revolutionary improvement to library self-service operations.
RFID technology uses radio waves to identify specific objects and read or write related data without requiring mechanical or optical contact. Once each book is equipped with an RFID tag, it is assigned a unique identity. This non-contact identification method can read multiple tags simultaneously, fundamentally transforming traditional library service workflows.
In terms of borrowing and returning efficiency, RFID demonstrates significant advantages. With barcode systems, processing each book typically takes 10–15 seconds. In contrast, RFID enables "one-step" batch processing: readers simply place multiple books within the sensing area of a self-service kiosk, and the system completes identification and registration of all items within 2–3 seconds. This means that borrowing or returning 10 books, which previously took nearly 3 minutes, can now be completed in under 30 seconds-an efficiency increase of more than six times. For public and academic libraries with high daily circulation, this greatly alleviates queues during peak hours.
RFID technology also simplifies the user experience. Previously, readers had to scan each book individually, paying attention to position and angle. Now, books can be placed casually within the sensing area, and the system automatically recognizes them-eliminating the need for item-by-item handling. This "user-friendly" approach lowers the technical barrier and improves adoption and satisfaction with self-service systems.
From a management perspective, RFID enables round-the-clock self-service. Many libraries have introduced 24-hour return stations, allowing users to return books at any time. Returned items can be automatically sorted by category through integrated sorting systems, significantly reducing staff workload and allowing librarians to focus more on professional services such as reference assistance and reading promotion.
RFID technology also enhances inventory management, shelving, and item tracking. With handheld readers, staff can scan entire shelves and read hundreds of items at once, dramatically improving inventory efficiency. Accurate location tracking further helps readers quickly find desired books, reducing search time.
According to Shenzhen Ascend IoT Technology Co., Ltd., RFID technology is reshaping library service models. It not only improves borrowing and returning efficiency but also serves as a critical foundation for libraries' transition toward intelligent and user-centric operations. As the technology continues to mature and costs decrease, RFID is expected to be widely adopted across more libraries, delivering increasingly convenient and efficient service experiences for readers.
