Hello everybody!
I am just writing my first demo program. But I have a problem with
sending the pin to the card.
The demo program should just give my name after you have entered you
pin.
What is wrong at my program?
It gets an error after it has sent the apdu for the pin :-(
I hope somebody can help me!
Thank you in advance.
Ciao
