Automatic Billing Trolley for an Enhanced Supermarket using RFID

Aim:

       The mainstay of this project is to design and develop an Automated Billing Trolley for Enhanced Supermarkets.

Introduction:

                 Supermarket is the place where customers come to purchase their daily using products And pay for that. So, there is a need to calculate how many products are sold and to generate The bill for the customer. “Supermarket Billing System” aims at developing into software that Can be used at places like Shopping malls, Supermarkets to easily operates the daily tasks of Taking the order, calculating the bill etc.

The main advantage of this project is that it converts all the manual work is time Consuming and error prone to fully automated system which helps in eliminating all the paper Work, saves time, improves customer services. It also speeds up various processes such as Addition of new items to the menu, deletion of items from the menu, modification of details of Items and calculation of bills thus providing convenience to the workers as well as customers.

In the development of the project, selection of an appropriate programming language and a Platform is of primary importance.In present days people are facing problem in shopping, this Supermarket Billing System project in C++ is a simple console application built without use of graphics. This project will help us to understand basically two things- use of stream class and file handling in C++ language.

This project is simple to understand, and the source code has been presented in an understandable manner. To make software fast in processing with the good user interface so that user can manage and change it, this should be used for long time without error and maintenance.This project is a traditional supermarket billing system with some added functionality.

This system is built for fast data processing and bill generation for supermarket customers. The Billing system consists of C++ and file handling concepts. The billing database is a vast collection of product name, price and other product specific data. A product when billed is searched from the database and its price is added to the bill based upon the product quantity. The system also contains discounted price while billing. The supermarket billing system is built to help supermarkets calculate and display bills and serve the customer in a faster and efficient manner

 Existing Work:

            Many Supermarket use this type of billing system for a decade. It is also improved Many times according to requirements of sellers and customers. It does the same work that is Calculating the bill gives it to the customer and maintain proper database. They are accurate in Calculation and printing they also generate records. The entire system involves human which leads to manual errors and time consumption.

Proposed System:

The proposed system consists a microcontroller connected with three push Buttons. Whenever the customer starts the shopping the customer loads the amount to their account via an android app installed in their mobile phones. The loaded cash value is updated to the cloud the same is displayed in the kit display. The customer will be pressing one of the push button before buying a product each and every product will be having a rfid tag whenever the product is added the respective amount will be added from the mobile wallet.

If the customer mistakenly taken a product they press a push button which reduces the cost and adds to the mobile wallet. The product name, cost, bill value will be displayed in the LCD display each and every time. When the shopping is completed the customer pushes another button to finish the shopping at the end of this process the details of the products purchased and the cost will be displayed in the app,so that the customer can verify the bill.
