Smart Trolley Using RFID & GSM

Abstract

A supermarket or a hypermarket is a form where wide variety of product items is available. Food, drinks, or any kind of domestic item might be included in this product category. Supermarkets' primary goals are to save customers time and ensure that all products are readily available. However, occasionally, customers become impatient while standing in line at the billing counter, and occasionally they become perplexed when comparing the total cost of all the products to their pre-billed budget. We have used Arduino to develop a smart trolley to solve these issues. The smart trolley system exists in the market, while our system has GSM technology which directly sends the shopping bill to your registered mobile number. Customers no longer have to wait in line to have their product items scanned for invoicing purposes thanks to this technology. If not, it functions just like a standard trolley. This tactic is used by hypermarkets and supermarkets as a way to draw in more consumers. In this project we are using Arduino uno r3 Board, lcd display and rf-id module. When the person wants any item must and should show the item to reader. RFID reader will read that number and compares that number in to the internal database and display the amount on to the lcd display. We can continuously add the item in to the trolley. Otherwise, if we are not interested any item we can show the same item to the reader. RFID reader will detect card and erase the item. lcd display will show the amount and item in trolley.
