I think power efficiency isn't a big issue for smart cards. If you
offer today's smart card buyer a choice between 50% power savings or
2% cost savings, he'll take the 2% cost savings without hesitating for
an instant. Question is, how many gates (chip area) does an ARM need
compared with the 8 bitter?

The desire to pay as little as possible for any piece of functionality
is as old as history and will always be present.
