Integrating flat bed scanner in asp.net

Think of it this way: when you visit a random web site, do you want it to have access to your hardware? Your scanner, your printer, your NAS? No - because some of them will take advantage and will do things you don't want.

So browsers do not have any access to hardware, for good reason. That measn you cannot do what you want. You will have to find a different solution to your problem.

Having said that, you could do it with an ActiveX control, if you wrote one. But since most computers are setup to actively reject ActiveX because of problems in the past with malicious software using them, you won't get it installed on many computers. And that would only work on Windows PCs anyway. What if the client was an Android tablet? Or a Mobile?
