I dislike yubikey because of the form factor.  While USB seems convenient
because every PC has lots of slots, USB keys are easily lost.  In addition, you
cannot print the owner name on them.

Fidesmo looks better, except for its depending on the Fidesmo Card App Store.

Isn't it possible to "burn" a blank card, somehow?
