For a card reader/writer on a serial interface or similar (e.g. USB), I
believe that the old antitrust rule of mandatory publication of interface
specs applies - thus all commands between the PC and the
reader/writer should be published. But then I'm looking at this from the
other side of the pond, where it has been very difficult to obtain this
sort of information from some reader/writer manufacturers.
Maybe one could use the same rule to force the publication of the
interface between card and reader/writer - and thus force application
and card OS suppliers to publish all the commands to, and responses
from, the cards.
