A Survey Paper on Smart Trolley Using RFID Technology

Abstract

India is one of the fastest growing economies in the world and aspires to become a 5 trillion dollar economy. E-commerce has surely spread itself and there have been many advancements in this field. The working class and most of our community prefers to go to malls or supermarkets and get their shopping done. Due to increasing populations, shopping is a cumbersome process as one has to wait in long queues to get their processing done. Clearly, it is a waste of time and a tedious affair. The major problem lies with the system of barcodes where every item is being scanned individually which makes the process slow and time consuming. RFID based shopping cart is a new way of shopping and avoiding long queues. The object would be tagged with a unique reader tag, which will be identified by the RFID reader attached to the trolley as the object is added to the cart. As the scanning is done the cost of the product will automatically be displayed on the screen attached to the cart. The bill value changes dynamically as the objects are added and subtracted.
