The problem with keeping the template on the smartcard and not letting it
off is that you then have to do the template match on the card, and doing
the template match requires a lot of CPU powercompared to what current
smartcards have. One system I'm familiar with needs a 50mhz processor
with floating point to do a template match in ~.2 second. Smartcards
can't get close to that performance yet, and getting the performance
and making it cheap enough to issue widely will take even longer.
Of course better algorithims, Moore's Law, etc will make it happen
soon enough.
