I know some of you will discourage scanning through a web page, unfortunately, it is a requirement.

I want to view my options in the situation, and maybe, some of you may have already gone through this and had a workable solution.

Problem is, we need to have a universal approach in scanning documents through the webpage without any external helper apps that does this for us.

I know this is a tall order, I would simply want to know the best next thing.

Thank you!

You can't do it with just a browser and JavaScript, full stop, you'll need to include something else -- a Java applet, a .Net "No Touch Deployment" application (mostly IE-only), a Flash or Shockwave application, something like that. In the Windows world, Flash has a huge installed base on browsers, but I don't know if it can do what you want (not knowing much about Flash). Next up would be a signed Java applet.

The user will then need to give your thingy permission to access local resources, a process that varies depending on the technology used. It's quite a simple process with a signed Java applet, much more involved and awkward for the end user with a .Net "No Touch Deployment" app.
