Kyle,
Using the Griaule SDK with LabVIEW is not trivial. It requires experience using ActiveX methods (or DLL calls), Event Callbacks and User Events to acquire an OLE reference to the image, and other tools (like the ones sold by George Zou) to transfer the OLE data into a LabVIEW picture control. [I'm currently working with Griaule to diagnose a random extraction error (-113).] Then, you have to convert the OLE variant data to a form that you can read later from your reference template database. You'll also need a database enrolling application for enrolling employees and their fingerprints. The Griaule SDK ships with an Access / VB example, but does not include queries, nor does it port directly to LabVIEW due to the aformentioned OLE variant limitation. (We used Microsoft SQL in lieu of Access.)
The good news is that Blue Ridge Test has already implemented the Microsoft reader with login features (either Name / Password only , Fingerprint only, or both) to track user operations, store their preferences, etc. into our standard multi-loop queued state machine.
After the setup phase of your experiment (i.e. configuring hardware & signal conditioning, verifying connectivity in MAX, demonstrating various portions in LabVIEW, etc.), you might consider your architecture before moving forward. "There's hardly anything more expensive than cheap" -Glenn Haege. We frequently have customers whose "simple engineering experiment" grew on them. And, interpetting bad LabVIEW code a year into a project can be a lot like deciphering abstract art. We would be happy to discuss your application with you before it gets to that point.
Take care,
