Just scan is a project I am currently doing as my final year project. It is a web application in which customers can order in a restaurant using their mobile device.
This project is a working in progress. The technology driving this application is Laravel PHP MVC framework and other several PHP and Laravel libraries. One of the issues I have encountered while building this application was creating a QR Code library which works on a web application and to resolved this, I created the user interface as a mobile app instead using Cordova and a few Cordova plugging available to speed up the development process.
