Hi Niyi,
For the mentioned card it should be okay to use it with in asynchronus mode, as it supports the T=0 protocol, which is defined to be asynchronus.
As there is a popular demand for a direct connection of smartcards to the arduino board, I will modify the code / description to reflect the needed wiring, when I'm able to get my hands on a smartcard slot. (I think one of my old set-top boxes is missing it's smart card slot in a minute. So if I'm not burning myself, unsoldering the smart card slot, I will start right away doing the needed modifications.)
If a SCLib version is available I will post an update here (But this might take a week or two :)).
regards
Angus
