Re: [keyple-dev] About using SAMs

[Max Paschetto <mpaschetto@xxxxxxxxx>]

Sorry for the self reply. I think that reading the
javax.smartcardio.CardTerminal documentation I got it right:
   "Note that physical card readers with slots for multiple cards are
represented by one CardTerminal object per such slot"
so I don't need any card extension but instead a configurable instance
of a Terminal that will allow me to access the four SAMs.
Thank you,
Max
