Smart Shop Cart

Abstract: Today, retail shopping demands increased convenience and efficiency to meet customer expectations. This paper presents a Smart Shop Cart system that integrates Arduino-based control, RFID technology, and sensor-driven human-following capabilities to automate and enhance the shopping experience. Utilizing RFID tags and readers, the system enables automatic product identification and real-time billing, minimizing manual effort and checkout time.

The human-following mechanism, based on ultrasonic and infrared sensors, allows the cart to autonomously track the shopper, providing hands-free mobility. Additionally, a voice assistant and a mobile application offer interactive control and real-time purchase monitoring. Experimental results demonstrate that the proposed system significantly improves shopping convenience and operational efficiency, making it a promising solution for smart retail environments.
