Smart Retail System with Secure Payment Using Internet of Things

The modern consumer shopping experience is evolving rapidly with the integration of technology into everyday tasks. In this paper, smart shopping cart system using Radio-Frequency Identification (RFID) technology with secured payment has been implemented to make shopping easier and faster. The system aims to enhance the efficiency and convenience of shopping by automating product counting and cost calculation processes. The cart equipped with RFID readers and sensors, facilitates real-time communication to increment and decrement product counts as items are added or removed. A final button initiates total cost calculation, enhancing accuracy and efficiency. With benefits including improved inventory management and checkout processes, the system promises to modernize the retail experience while reducing operational costs. This system not only simplifies the shopping experience for customers but also helps stores manage their inventory better and save money on operational costs, making shopping more convenient and efficient for everyone involved.
