Design and implementation of low-cost uhf rfid inventory management system

Abstract

In this study, an ultra-high frequency (UHF), radio frequency identification (RFID) system has been performed for the purpose of inventory management, which is suitable for low cost and flexible use. With the system proposed, the security and permissions of the products in the inventory were effectively managed from a single operator point. For the UHF RFID system, two application points were created. One is the central point, which provides user permissions, and the other is the security point, which controls entrances and exits. Its aim is to analyze the data obtained from RFID tags from a single point. Communication between the operator and the long-distance UHF RFID reader is provided by the RS485 serial communication standard. An efficient data processing structure was used to increase stability and making data meaningful for the transformation data which was obtained from UHF RFID at the security point. A flexible graphical user interface (GUI) has been created for the UHF RFID inventory management system. The performance of the system customized for library inventory management has been successfully tested over real usage scenarios.
