This is only possible for readers, that can handle SM themselves. Those
readers exist for example for the new German Identity card. If you are
handling SM with OpenSC, you need to do PIN-Management without the help
of the reader's pinpad. Old readers (PCSCv1?) had the capabilities to
send the PIN back to the application, which was potentially risky.
