Bio Approval Workflow, aka Secure Purchase Order System (SPOS), consists of a WPF client using the Windows 7 Biometric Service API. The client interfaces with a back-end database to implement a secure purchase order approval system. PO approval requires
a valid fingerprint scan.
Please note: the Visual Studio solution and project files assume that the latest Win 7 SDK and DDK are installed in the default locations. If your environment is different, update those settings accordingly, or the solution won't build. We recommend running
the project from within Visual Studio 2008 Professional, since SPOS uses SQL Express by default.
