This is a very basic version and the application is still under development.
So, what does it do ?
It allows you to scan a QR Code ( If you don't know what a QR code is, go here : http://en.wikipedia.org/wiki/QR_code ) and retrieves information based on it from a database.
This application comes in two parts, one is the Android app, and the other, a PHP file which has to be set up on your own web server.
How is this app useful ?
You can use it as any kind of custom tag and scan system.
Identity cards for events, Inventory tagging with info and prices, Student grades or course information tagging, etc.
Follow the guide at www.enarsee.com/qrscanner to set up your application.
