You would DEFINATELY need to use serial as the Z is not USB host capable. Beyond that, I have no advice As i\'ve never heard of anyone trying htis. Actualy, other than a few cell phones and a realy stupid mouse pad i\'ve never seen anything thaat actualy \"used\" smart cards. Even the credit cards with the sim chips are a waste for 99.9% of people because no credit card machines or ATM\'s actualy use them, they\'re just decoration for all intents and purposes, unless you have a smart card reader hooked to your pc and short at one of 3 or 4 online retailers that will let you use a smart card reader to enter info.
Anyway, what are you ding with smart cards, I\'m rather curious.
