I still think it wouldn't be bad if you could give an example of what does not work and what does, because then, perhaps, someone would be willing to help implement the missing (or wrong) functionality – especially as you've already written your own code. As far as debit cards are concerned (EMV), my experience is that opensc-explorer does not work because it tries to select the Master File upon startup. A small patch to let the user choose a different file, or not file at all, at startup, would overcome that. (Surely there would be other problems later.) I'm unsure about your example of "cat 2F00, cat 2F01", because I'm under the impression that EMV cards use file selction by name (and not by file ID), but I may very well be wrong here. > There is still the question, if this is the right place for a command > not defined by iso.

Yes, this is possible in principle, although many sensible COS manufacturers (or even developers writing BasicCard/JavaCard applets) would question the opportunity of defining a proprietary command overriding an international standard (EN 726) that's been in place for so long. But the point is moot, because… > 2. Not even a single card driver overrides iso_ops->give_random. So > every driver would send this command down to the card. Which is not a > good idea (see point one). …as far as I am able to tell, this means that no driver at all will ever send this command to the card, until someone decides to use it somewhere in the code. That said, I'll reiterate: if give_random is significantly controversial, I won't object to removing it, as it isn't being used.
