I was playing with my fingerprint reader this weekend and thought I would share what I have worked on. I began this process like I do many others by doing a search to see if anyone has already implemented what I wanted to do. My search turned up an article by Scott Hanselman (http://blogs.msdn.com/coding4fun/archive/2007/03/06/1815291.aspx). Here he builds an application to warehouse his families fingerprints. He also talks about a SDK called GrFinger (http://www.griaule.com/page/en-us/grfinger_fingerprint_sdk). After spending some time looking at his code, and the sample that shipped with GrFinger, I decided to embark on writing my own.
The requirements:
1) The software shall capture a fingerprint using the MS Fingerprint Reader (http://www.microsoft.com/hardware/mouseandkeyboard/productdetails.aspx?pid=093)
2) The software shall be able to save a person’s prints and name to a sql server database
3) The software shall be able to lookup a person by their fingerprints
The solution: See zip file for complete source (http://www.onetug.org/DNN/Portals/0/member_files/Onetug.Identity.zip).
