You miss the costs. For smart cards:
- cost and hassle of buying a reader (although your keyboard idea
offsets this)
- hassle of installing software
- hassle of only being able to get access where there's a card reader
For manual challenge-response cards:
- hassle of typing stuff into them and reading a LCD
For both types:
- cost and hassle of getting cards
- hassle of guarding cards from pickpockets and burglars
- hassle of making sure you always have your card when and where you
need it
- hassle involved when you inevitably lose your card
This is arrayed against a plain password which can be handled easily by
any software system that can do console IO. And for which the user can
chose the level of security, from post-it note to memorization.
