The paper describes a system that provides the guidance for them to identify and purchase their products in the supermarket. Quick Response code (QR code) technology is implemented to identify the product which is far better than existing RFID technology . The audio instructions will assist them inside the supermarket based on the real time situations. It provide obstacle detection to navigate inside the supermarket without colliding with any 3D object. To make the supermarket in a smarter way the billing system is automated.
