C# or C++ program to Get a Finger print template stored in a certain database and compare it with a fingerprint captured from a sensor

Hello. I need a program written in any of the two languages. The program has to do the following: 1) First it has to retrieve a Finger Print template from a database (the database is external; ie not on the FPS itself) 2) Asks the user to scan their finger on the FPS (Finger Print Sensor) 3) Once the finger has been scanned it compares it with the template of step 1 and returns a result (either a good match or bad match) I am using the following sensor: "Fingerprint Scanner TTL GT511C3 - 3.3V to 6V" The following is a link to the sensor: [login to view URL]
