Hi
From your description this is not a web application, rather it is a desktop application,
In a desktop application, you can easily add functionality of scanning an image from the scanner, but in a web application you need to scan manually then upload the image.
If you want to make this a web application, I can build a tool to scan and upload the image.
We will build for you a nice looking we or desktop application
Please talk with me in PM, so we can decide which choice you have to pick
Thanks in advance
