grue, it's obvious that you want to argue with me about other people's proposals. So here, watch a video about the hardware I'm suggesting:

no, i'm arguing about how secure a smartcard system (in general) can be. it's very hard to keep your keys secure if the terminal that you're using can't be trusted. as long as the interface between the card and the user isn't protected, there will always be a risk of a man-in-the-middle attack. if you have a solution to prevent the attack i mentioned earlier, i will be glad to hear it.

One of these measures is to house your security information on a computer chip within the card as opposed to displaying it on the card. Another is a unique display window that reveals a security code necessary to complete a transaction. Each code can only be used once, so even if your card information were stolen, a thief would be unable to effect a transaction without having physical possession of the card and its security code. This window can also display account information such as your last transaction, your balance, how much you have spent this month, even messages from your bank.

too bad i got both
