# TWAIN acquisition demo

This sample application demonstrates how to acquire documents directly in a DocuVieware based web application.

[Try demo](https://www.docuvieware-demo.com/twain_demo.aspx)

Web browsers can’t access the system at the level needed to interact with a scanning device, so a small program must be installed on first use. Its only purpose is to fill the gap between the browser and the acquisition device.

Once installed, it starts automatically with Windows, runs silently in the background, and has a small footprint.

> The TWAIN connector software installation package is provided as an MSI package so end users can install it and system administrators can deploy it at a larger scale.

Using the DocuVieware TWAIN acquisition feature, you can create a new document or append pages to an existing one at any position.

This demo application also includes a button to generate the acquired document as a PDF/A-1b compliant document, enabling long-term archiving.
