Iot application based advanced shopping trolley

Abstract

Reducing the time consumed while waiting in long queues during the checkout process in a supermarket is one of the core objectives in improving the shopping experience of customers. In this paper we propose the use of RFID embedded with the shopping cart to design a smart shopping system. All the shopping carts in the mall are coupled with RFID tags. When a product which also has an RFID tag is placed in the cart the billing information with respect to that cart is updated by reading the details of the respective product.The malls are installed with smart shelves which are also coupled with RFID readers. This will help in maintaining an inventory list of all the products in the mall and hence improve stock maintenance.In addition to this setting, an LCD display is also installed in the cart which displays the details of available products in that cart and the overall price of all the items. A mobile Point of Sale is maintained in the cart so that the customer can make the payment without actually having to wait in a long queue for the checkout process. All the processed information is maintained in a database so that it be used for analytical purposes in the future.
