Smartcard access library

Hi Angus,
I'm trying to use your library for a project. I am connecting the smartcard (an ACOS3 contact card 64KB EEPROM) directly to the Arduino without any chip. I want to know which mode, synchronous or asynchronus mode is suitable for the card?
A schematic for direct connecting of the contact pins to the Arduino would be of help too.The card is ISO7816-1,2,3 compliant 8-contact module supporting T=0 direct protocol.

Thanks a lot.
Niyi.
