Various inventory management applications based on RFID technology, such as warehouse center bulk goods rapid inventory systems, retail store shelf intelligent inspection systems, library collection document efficient counting systems, logistics transfer station parcel dynamic verification systems, and enterprise fixed asset real-time inventory and positioning systems, etc. These applications deeply meet the core needs of "efficiency, accuracy, and real-time performance" for inventory in different scenarios. Leveraging the unique advantages of RFID technology—non-contact identification, simultaneous reading of multiple tags, and rapid data transmission—they completely transform the cumbersome traditional model of manual item-by-item counting, handwritten recording, and manual data entry. In warehousing scenarios, staff only need to carry a handheld RFID reader and move between shelves to complete information collection and quantity verification of materials on an entire row of shelves in seconds, increasing inventory efficiency by dozens of times compared to manual work. In retail stores, fixed RFID readers can automatically scan shelf goods, real-time feedback abnormal situations such as stockouts and misplacements, helping stores replenish goods in a timely manner and optimize merchandise display. In libraries, tens of thousands of books can be quickly counted and their borrowing status verified through RFID handheld terminals or channel-type readers, greatly reducing the workload of librarians. In addition, RFID inventory data can be synchronized to the backend management system in real time, automatically generating inventory reports and marking discrepancy items. This not only avoids human errors caused by manual recording but also realizes digital and visual management of the inventory process, providing accurate data support for subsequent inventory optimization and asset allocation, and significantly reducing management costs and operational risks.
