I prepare a hard-lock key for my PC mod which will shutdown all external USB ports whenever i wish. I could have used some sort of key-lock, or a mod of my keycode lock, but instead i decided to use something more fancy - I decided to use a smart-card reader to do the job.
Thew first step is to get control over smart-cards. After reading some documents that Panagiotis provided me (thanks _Pike), i began experimenting with smartcards and more specifically with Greek telecards, and i wrote a detailed theory regarding phonecard smart-cards. Eventually, i made this first circuit which reads the content of a telecard.

Ok but this in not usefull
make a PIC telephone card
wou will make a telecard sised pcb ( a little bit bigger to put the pic on it )
and it will have an PIC and CR2032 only
HOT in heaven!
