Hi,

Since PC/SC is able to read the ATR, it means that your card is
an asynchronous card, not a synchronous card.
There are some memory cards that can be 'Asynchronously' accessed using PC/SC.
Looking at the ATR, it seems to me you have a STARCOS S21 card.
You should probably use the STARCOS APDU's instead of the SLE4428 ones ?

Regards,

Serge
