Fastbill is a web application for various retailers like shoppers drungs mart,walmart, Dollarama, D-Mart etc. In this application owner or employee of any retailers who are using this application can scan barcode of products purchased by customers and generate bill for the customers.
In this application I have used Aurdio to scan barcode of products.For this application, backend implemented in nodeJS and mongodb used as a database.
Moreover, Using this application retailers can keep purchased history of products and monthly reports.
