Hi Andre!

Thanks for the remarks!

Good to hear. Are you using reader-pcsc?

Speaking for myself here – examples and/or log traces would be
helpful, I think. What doesn't work with your card, and you'd like to
see improved?

It isn't, to tell the truth; as the comment states, that APDU is not
from ISO 7816, but rather from EN 726-3 (or ETSI TS 101 206-3, if you
wish).

The driver isn't using it any longer (as I'm looking at SM separately,
following Viktor's work), so I don't "need" it. It may make sense to
leave it there, though, as it is clearly marked not to be from ISO
7816 but from a different standard.

Greetings,
