Smart trolleys represent an innovative approach to enhancing the shopping experience in supermarkets by integrating advanced technologies like IoT, RFID, and AI. These trolleys are equipped with sensors and automated systems to identify, track, and calculate the cost of items placed in them, eliminating the need for manual checkout. They can provide real-time updates on item prices, promotions, and personalized recommendations based on customer preferences. By streamlining the shopping process, smart trolleys significantly reduce waiting times and improve customer convenience. Additionally, these trolleys can assist in inventory management by relaying data to the store's backend systems. The inclusion of features like navigation aids and voice assistance caters to differently-abled shoppers, ensuring accessibility. With enhanced security protocols, they prevent theft and billing errors. The adoption of smart trolleys promotes operational efficiency and sustainability by encouraging paperless transactions. As a transformative tool, they are reshaping the future of retail, blending technology with customer-centric solutions.
