I know the windows application, but i don't know how to integrate to my web application
There is no direct way to integrate a hardware device to a web application. Having a device integrated works good and with ease with a Winforms or WPF desktop application. Integrating with an ASP.NET application would be difficult.

You need a SDK for it, either a 3rd party or write your own!
Have a look at this: Free cource code Fingerprint comparison[^]

Look at this article: Fingerprint Reader Integration using the M2SYS SDK[^]

You can explore the following class: MSDN: Biometrics Class[^]

Also look at this: C# wrapped Biometric API[^]

UPDATE: Just a second thought, using Silverlight (if possible option) might help.

I solved this problem, initially, creating a desktop app (winform) and deploying it using clickonce.

This way you have a desktop app, but easy to call and deploy from a URL.

Also you can pass arguments to the application using querystring parameters, so when the app launch, it can retrieve some user id and call some web service to retrieve user details and then update it iback to the database.

Something like http://www.yourdomain.com/downloads/MyDesltopApp.application?userID=999

The above URL is an example of a clickonce desktop app, published and accepting parameters.

this way, you could easily integrate your web application simply creating dynamically a link similar to my example.

When the user clicks on that link or button or whatever, the app launch downloading, installing and running and reading your parameter.

Hope this helps.
