title: C# - Fingerprint Biometrics
body: <p>We are wanting to add support for fingerprint authentication in a .Net 3.5 application.</p>
  
  <p>We currently are only using the sdk from <a href="http://www.griaulebiometrics.com/" rel="noreferrer">Griaule</a>.  But this only supports like 5 usb plug-and-play devices.  We are wanting to support most readers included with laptops, tablets, etc.</p>
  
  <p>Is there a universal way to support many devices?  I know there is a new standard starting with Windows 7, but we want to support XP and higher.</p>
  
  <p>Is there even a .Net SDK out there for UPEK or Authentec devices?</p>
  
  <p>Any ideas or help would be appreciated.</p>
