Abstract

A shopping mall is a place that sells a wide range of products. On holidays and weekends, malls get a lot of foot traffic. When there are special offers and discounts, the rush is much greater. With the use of a shopping cart, numerous things are purchased in shopping malls or market. However, when it comes time to pay the final bill payment, the customer must proceed to the cashier to make payment and the shopping mall does not have sufficient counters that are able to handle all of the customers. Additionally, scanning each and every product of every consumer becomes a massive process, resulting in long lines. This led to big crowds at shopping malls. There are also times when customers become confused when comparing the total price of all the products to the budget that they have in their wallet before billing. To solve these problems, it is proposed to implement a smart shopping cart, which would involve developing existing shopping carts such that it will contain a barcode scanner and allow customers to scan product barcodes. As a result, the product id, name, price, and quantity will be automatically displayed on the LCD and an application. Here, customers can also keep the track on the total cost of products according to their budget. Then, the final bill will be automated to the application. In this manner, customer can directly pay the money at the billing counter and depart with the commodities he or she has bought, which saves the customer's time and eliminates the need for them to wait in a lengthy line in order to pay for their purchases. This concept which is ‘Smart Shopping Cart’ is proposed to keep track the budget from the total cost of added products, improve the speed, reducing the long waiting queue and also to save time.
