 TWAIN driver TWAIN is the most widely used protocol for physical document scanners. Almost all scanners in the market come with a TWAIN driver and are supported by TWAIN applications like the Dynamic Web TWAIN SDK.
 
-`WIA` refers to <a href="https://docs.microsoft.com/en-us/windows/win32/wia/-wia-startpage" target="_blank">Windows Image Acquisition</a>, which is the still image acquisition platform in the Windows family that enables imaging/graphics applications to interact with imaging hardware and standardizes the interaction between different applications and scanners.
+`WIA` stands for <a href="https://docs.microsoft.com/en-us/windows/win32/wia/-wia-startpage" target="_blank">Windows Image Acquisition</a>, which is a Microsoft driver model for capturing digital images from various devices, such as scanners, cameras and other imaging devices. The WIA protocol is built-in and supported by Windows OS, so no extra driver installation is required. WIA offers standardized hardware compatibility and a stable driver environment, making it easier to integrate imaging capabilities into web scanning applications. 
+
+Prior to Dynamic Web TWAIN version 18.2, WIA drivers are not officially supported. But `WIA` devices can be used by `TWAIN` applications like `Dynamic Web TWAIN` through a `TWAIN compatibility layer`. This means `WIA` is not supported natively; therefore, when a device supports both `TWAIN` and `WIA`, `TWAIN` is the better option.
+
+As of Dynamic Web TWAIN version 18.2, we officially support WIA 2.0 drivers. To make sure your web application works with WIA scanner drivers, please refer to the article: <a href="{{site.faq}}support-wia-scanner-drivers.html" target="_blank">How do I support WIA scanner drivers in my application?</a>

-By comparison, `WIA` can only control a very limited set of general capabilities of the device while `TWAIN` can control all standard and even custom capabilities of the device. Another thing is that `TWAIN` has three transfer modes (Native, Memory, File), while `WIA` only has two (Memory, File).

+## How do I support WIA scanner drivers in my application?
+
+Prior to Dynamic Web TWAIN version 18.2, WIA drivers are not supported and TWAIN drivers are recommended. Please refer to <a href="{{site.faq}}difference-between-Twain-and-wia.html" target="_blank">this article</a> for the differences between WIA and TWAIN drivers.
+
+As of Dynamic Web TWAIN version 18.2, we officially support WIA 2.0. By comparison, `WIA` can only control a very limited set of general capabilities of the device, while `TWAIN` can control all standard and even custom capabilities of the device. In addition, `WIA` has only two transfer modes (Memory, File), while `TWAIN` has three (Native, Memory, File).
+
+Since Dynamic Web TWAIN v18.0, we introduced a new set of scanner related APIs.
+To support WIA 2.0, 
+- If your application is already using the new set of APIs below, no application change is required.
+- If not, replace the old APIs with the matching new APIs.

+### Difference between the WIASCANNER and WIATWAINSCANNER DeviceType
+To support the WIA protocol in v18.2+, we added a new Enumaration `WIASCANNER` to [Dynamsoft.DWT.EnumDWT_DeviceType](https://www.dynamsoft.com/web-twain/docs/info/api/Dynamsoft_Enum.html?ver=latest&&cVer=true#dynamsoftdwtenumdwt_devicetype) . The enumaration named `WIATWAINSCANNER` represents WIA source mapped through the TWAIN protocol after packaging by Microsoft. It was used in previous versions of Dynamic Web TWAIN and it will continue to be supported.
