I was looking at a credit card calculator the other day. It was the template for the perfect smart card: - It was the same size and thickness of a credit card and could easily fit in a wallet. - It had an lcd display window. - It has a touch keypad built under the surface of the skin. The only upgrades required to have a crypto-card would be a more powerful processor, tamper-proof case, backup mechanism, static memory, and an interface for a card reader. Instead of entering your passphrase on the keyboard of your computer, you enter it on the card itself. The card digitally signs the message (payment order or user authentication) sent to it from the computer, and then sends the signed message back. It should be possible. The high price of smart cards is merely a matter of lack of market depth at this point. This stuff could definitely be crammed into a cell phone or a palm pilot. In fact, cell phones might be the best way to handle digital money. They don't have the virus issues associated with windows systems. People who have them carry them with them everywhere, and they don't run lots of other applications.
