Delphi USB fingerprint scanner demo

I need a simple demo Delphi program built which will scan a fingerprint and save it as a template file. It must also scan a fingerprint and do a 1 to 1 compare of a fingerprint template on file indicating a match or mismatch. The demo program must be written in Delphi, nothing else. It is also acceptable but less preferable to write a C++ dll which can be called from a Delphi program. The program must work with the DigitalPersona U.are.U 4500 Finger Print Reader. You can use the free One touch SDK. If you will use a third-party library I need to know which one.
