IoT Based Smart Shopping Cart

Physically challenged and senior citizens find it difficult to push heavily loaded carts around the supermarket. To combat this, we have implemented an autonomous shopping cart that supersedes the existing shopping trolley. This autonomous cart can manoeuvre around without the need of pushing it by using multiple ultrasonic sensors. To avoid long queues at the billing counters and also to reduce the workload of the employees at the supermarket, we have implemented a billing system. Scanning is incorporated in the cart itself, thus reducing the time wasted by customers at the billing counter. This billing system uses RFID (Radio Frequency Identification) to scan products. Products scanned in the cart are sent to the computers installed in the supermarket using a Wi-Fi module. The Automated Shopping Cart thereby eases the shopping experience of customers and reduces the manpower employed in supermarkets. The significant benefit of using an automated cart is that customers can move swiftly through the cash counter and check out independently.
