Hi Prem Shah,
>>How do I integrate smarcard(HID Global OMNIKEY 3x21 Smart Card Reader 0) in C#/WPF Application.
I could not find any sample about integrate smarcard in WPF application, I would suggest that you could contact with manufacturer again and check if they have any API to access it via WPF.
Best regards,
Zhanglong
