I had this thought years ago. A smartcard coupled with a biometric seems easier to use and more secure.
Even just a card. You can only have one per person (as opposed to passwords that can have infinite copies and are likely to be unknowingly compromised) and if a card is lost, it can be expected that it will be replaced shortly so long as the replacement process is painless which seals the leak.
