Abstract :
Nowadays, People are living more fast-paced in everyday life. For example, going out for shopping can sometimes be a problem. In the process of purchasing, Consumers cannot know the value of the products they added to their carts, hey will know only the price of each product which bring the products that they have chosen may encounter problems which is the value may greater than they prepared and may interfere with the payment process, cause wasting of time.
From the problems mentioned above, the organizers have done a project to calculate the product price for a shopping cart (Digital Cart) to be more suitable and more convenient to use. For the first step, the organizer collects product price information and barcodes to create the database. When the user starts the transaction, the system will retrieve the data saved in the model and display it through the display screen showing to the user. In the last step, the author has created a 3D Box to insert the model. And testing the model as efficiently as possible The experimental result found the digital cart can calculate the product price accurately and efficiently by scanning barcodes. But sometimes there might be an error with the barcode scanner module.
