Retail stores and shopping centers serve as crucial hubs for fulfilling the community's daily needs. One significant benefit of visiting these centers is the ability for customers to physically interact with products before making purchasing decisions. However, challenges such as long checkout queues often detract from this experience, consuming valuable time and energy. To address these issues, we propose implementing a Sensor Fusion System aimed at enhancing future retail store technology. This system leverages Radio Frequency Identification (RFID), a core component of the Internet of Things (IoT), within shopping centers or retail stores. RFID technology facilitates the tracking of items through radio frequency signals, which are embedded in shopping carts to detect the contents therein. This real-time tracking enables seamless recording of shopping bills based on the items present in the smart store basket. This innovation promises to streamline the shopping experience by minimizing checkout times and enhancing operational efficiency within retail environments.
