Smart Trolley Using Automated Billing Interface

Shopping is both a regular and a tedious process, especially in a supermarket. Though the internet has revolutionized the way of retail shopping, online shopping does not look to fully replace the brick and mortar stores. However, large crowd during peak hours and on public holidays generally led to longer billing time in the retail stores makes customers impatient, and also affects overall shopping experience. Here, the present work presents a novel and smart design of shopping trolley using RFID technology and Arduino which facilitates shoppers to scan the products on their own. Furthermore, the proposed system also provide a web interface for generating the bill and provide an automated payment interface for the customer. Subsequently, the proposed model is expected to ease off queue pressure at billing counters, and offers enhanced shopping experience to the customers. The same has been realized with the help of module ESP8266, which provides microcontrollers connection to 2.4 GHz Wi-Fi. The results show reduced billing time and enhanced customer experience. Additionally, fixed-cost per store is reduced that allows for further leveraging of existing resources and possible expansion of stores.
