    Web browsers do not support Twain scanning on their own. You will definitely need some sort of component or plug-in with higher level permissions to be installed on the PC to communicate with the Twain source (scanner) and deliver the scanned images to the browser-based application. Using twain requires access to the local hardware which has traditionally been unavailable to web developers. There has been at least one open source attempt (http://twainx.sourceforge.net/) but it only works with MS IE, and only with older versions of it. – LEADTOOLS Support Feb 27 '15 at 01:06
  • If you don't want to pay for sophisticated commercial SDKs, why don't you make it yourself? Do you know how to implement a desktop TWAIN app in .NET? – yushulx Feb 27 '15 at 08:20
