BiometricDevice CSharp

This document is a C# program that demonstrates how to initialize, capture, and close a fingerprint scanning device using the Nitgen SDK. It includes methods for initializing the device, capturing fingerprint data, and handling errors during these processes. The program outputs messages to the console to indicate the status of each operation.
