I  read  a smartcard is simply a chip card. Why is it save, what's a
PIN? Say I'm using it on a PC with a trojan in the background
that logs my keystrokes (my password) and can send data (my key)
via  internet  to  an attacker. How is access restricted to the key by
the smartcard?

Since  the PC is "isolated" from the net, I don't need to be afraid of
software    keyloggers,    trojans   etc.   I'm   only  fulnerable  to
physical/hardware attacks  which  are  easier  to  notice for a person
who's no computer expert.
