If you want to know in which reader is inserted the card you are
looking for you can use SCardListReaders() to list the readers and
then SCardGetStatusChange() to get the ATR of the cards in the
SCardLocateCardsByATR() is not provided by pcsc-lite. But it should
not be too complex to add it.
If you want it to be implemented just contact me.
