IIRC, "smartcards".

All you need is a way to connect the ends.

HTTP. RMI. Web services.

If your card reader is here, and your server is there, you need one of two things 
to connect the two - a really long wire or a radio or a network. Okay, three.

Presumably your reader is on the "client" side of the client-server exchange. You 
need hardware to connect it to the connection, so to speak.

Example I use - I sometimes debug smartphones. The communication locally would 
be between the phone and the PC via a socket that a driver translates to USB signals.

Now I have my test environment on a server over there, but my phone on my 
workstation over here. I connect to there from here via SSH, with reverse port-forwarding 
to convince the server that port 6666 (for example) is the one at my end. So the server 
talks over an SSH tunnel to my port 6666 thinking it's its own local 6666. It's just 
like being there, only slower.
