Hi,
As promised I updated the SCLib to be able to talk directly to a smartcard, without the need to have any interface chip (Just be carefull not to fry any 3.3V GSM cards etc., as currently it works with 5V).
The updated release (0.0.4) can be found here Smartcard Lib for Arduino compat. boards / Wiki / Home. I also provided a schematic how to connect a smartcard slot to the Arduino.
Regards
Angus
