DESIGN AND IMPLEMENTATION OF AN IOT BASED SMART TROLLEY AND BILLING SYSTEM FOR SUPER SHOP

Abstract

Supermarkets are becoming more popular in today's consumer environment, drawing a varied range of people owing to their vast product offerings. Supermarkets provide a large variety of things, including fresh vegetables, meats, dairy, and packaged goods, as well as home essentials, making them an excellent one-stop destination for completing all shopping at once. This convenience, however, is not without its drawbacks. Long lineups can make shopping experiences unpleasant, leading supermarkets to utilize techniques such as technological improvements to enhance the shopping experience—especially during peak periods when many offers are available. The billing method is typically time-consuming and hectic, requiring the inclusion of more human resources in the billing area. Customers often have trouble operating excessively loaded carts. Manual computations of purchases and budget comparisons until the scanning process in the invoicing area add another degree of aggravation. To address these concerns, an extraordinary idea encompassed with IoT and RFID scanners are implemented into shopping trolley. As clients load items into the trolley, the RFID reader automatically reads product data such as item names, prices, and weights. A speaker will declare the goods that buyers have chosen, as well as their price and weight. This information is then shown on a screen, allowing buyers to inspect goods and alter pricing by rescanning. Furthermore, the trolley is designed to move, eliminating the need for customer to push it back and forth. Customers may pay with cards while shopping by simply putting the card in front of the RFID, and the payment is completed in seconds. An SMS will be delivered to the customer's phone number to confirm the payment, and the payment procedure will also trigger an announcement over the speaker if the card does not have an adequate balance. When a customer is done shopping, they can easily take their cart to the payment area. This cuts down on the time-consuming physical counting process and makes shopping less tiring, especially for older customers.
