The main applications of javacard involve public key cryptography which
needs fast multiplication.  There were discussions on this newsgroup a
while back about the GA144's power efficiency at multiplication compared
with a conventional low powered DSP and they were either inconclusive or
unfavorable to the GA144 depending on your point of view.  The issue is
that DSP's have dedicated multiplication hardware while the GA144 takes
an efficiency hit by having to multiply in software.

There were two models of the java ibutton.  One had 6k of ram and the
other had 132k if I remember right.  I think they both used an
8051-derived core.

The same sorts of things smart cards are used for (authentication tokens
mostly), but they had extra capabilities because of the sealed RTC, and
they also supposedly were more secure against certain types of attacks,
since the processor was not accessible to the outside except through the
1-wire interface.
