In recent years, due to labor shortages, cash registers and other such facilities have become unmanned, and there is a growing need for automation in the prevention of product theft and inventory control.
Existing gate-based anti-theft systems often malfunctioned and were unable to determine the location of sensitive merchandise, causing inconvenience to customers and employees.
In this system, we have succeeded in using four UHF RFID antennas to accurately track the location of tagged objects based on their propagation strength, and display the information in real time using Unity visualization software. This paper describes the details of the method and discusses its practicality. |
