Smart card

> Smartcards are a pain in the ass.

A funny but completely accurate way to put it:

When your private key is on your laptop, you never put it through the
wash by accident.

(I can tell you from personal experience most smartcards handle being
washed just fine, but the static charges they're exposed to in the dryer
will often fry them.)

Once you make a smartcard into a credit card, or a dongle you hang off
your keychain, you open yourself up to some very interesting failure
modes -- many of which you won't see coming.  For instance, I once tried
to pay for a hotel with my kernelconcepts card, because it was located
adjacent to my credit card and I pulled it out by accident.
