Secure an app by USB and server using C#

I am developing windows form software in which users are required to have a unique USB to run it, or they need to connect to a server to get permission. I need to make the GUI look beautiful and professional also. It doesn't take a long time I guess as long as you know it before.

Taidot: C# -ohjelmointi
