WingScan® Features

Web Based Scanning (in browser)

WingScan is a JavaScript API and Windows (v7+) Service for communicating directly with a TWAIN device through a web application.

WingScan allows you can scan from a web browser - this improves security and enables end users to scan directly to a repository without the need to save locally first. It is accomplished by using a lightweight http server on the scanning computer that the browser can communicate with and a handler on the serverside.  WingScan is a stand alone product with a streamlined viewer - however when you combine WingScan with our DotImage SDK you have superior web based scanning combined with powerful viewing controls to make capturing and processing documents effortless. 

  • Browser-based Scanning - WingScan includes fully customizable browser controls that allow end users to submit documents directly from their scanners
  • Viewing -- WingScan includes an HTML5/JavaScript document viewer for scanned documents.  For a more robust viewing experience, see our DotImage SDK.
  • Easy installation -- WingScan includes a simple process for installing the Windows Service on the client machine.
  • Browser Support - Firefox, and Chrome
