Coding4Fun: Interfacing with a Microsoft FingerPrint Reader

Here's a new Coding4Fun article I did on interfacing with your Microsoft FingerPrint Reader. I used the very easy GrFinger SDK from Griaule and I want to thank them for their help with my questions for this article. They've got a fine product that's very easy to code to and their drivers were rock solid for me. Check them out for if you're interfacing your .NET application to any FingerPrint reader, not just Microsoft's.

"In this installment of the "Some Assembly Required" column, Scott Hanselman creates a Family Fingerprint Manager using .NET 2.0 that interfaces with the Microsoft Fingerprint Reader and the GrFinger SDK from Griaule."

In the interest of preparedness, I figured we needed to get the family fingerprinted and to put those finger prints with my "Preparedness USB Getaway Key" and in the safety deposit box, so I created a family fingerprinter.

It's a pretty simple application, I save the fingerprints in an XML file for portability. Note the "auto next finger" feature, so you can fingerprint your friends and relatives just like the cops do. ;) Enjoy.

Hi Scott, I really think that the Coding4Fun and the "Some assembly required" series are a fantastic way to get enthusiasts back into the passion that you felt when your first "hello world" application compiled and ran! Thanks for your invaluable time and efforts!

Thanks! That's very kind of you to say. Be sure to tell *danielfe AT microsoft* - he's appreciate it.

Doh! Scott *finally* makes a post including his fingerprints and he blurs them out. So much for stealing his identity. Pfft.

I used a great sdk from neurotechnologija called verifinger.(
It can do about 45K fingerprint a second when it comes to recognition. It allows control of sensitivity to fingerprint features. They also sell a facial recognition sdk called verilook

Hi Scott,

I found your app a few days ago, because i want to do something similar to that but just with one finger. I've been having troubles with your example because i can make it work on my computer; maybe I am missing something because I am new using the fingerprint reader and I don't understand very well how to manage it.

It would be too much for asking the complete code just the way it works for you? I'm a little bit desperate, hope you cauld help me

P.S. Sorry about my poor English
