Smartcards

Hi everyone. It would be good if cc had a smartcard. I know you can use floppy disks as them.

It would be useful for the following things:

1: You could use it to logon to computers

2: Door lock

3: Banks and stuff

And other stuff.

So guys what do you think?

Based on your description I don't see a need for them - all your suggestions can be done with floppies. It would be helpful if you described what you think smartcards should actually be and how they should be different than floppies. Maybe start with something like WORM media and go from there.
