Abstract: In general the shopping and billing of each and every products or a commodity is done by scanning the Barcode or the QR code which is present on the tag of each commodity. Here our concern is about the customer who love shopping but are frustrated by the long queues at the billing counter, this absolutely waste of time and if the particular product is not available at the shopping center the customer have to move to another shopping destination which again increases the time complexity and there is also increase in the Traffic as user have to travel again and the parking problem. In this paper we have come up with an Android application. The application helps the user and the retailer in the easy shopping and reducing the conjunction at the billing area.
