I disagree. The purpose of this device is to protect the key from being copied and to sign requests. Providing the correct address is a concern of the recipient of the funds, if the POS terminal is infected and the store does not get its money then it has nothing to do with the card.

I think this smartcard is solving a very specific problem and that other concerns must be addressed elsewhere.

Well, I'm targeting traditional PC-s with this solution and the concern for trojans, sitting between the screen and keyboard and the key-container device is a real concern. Meaning that if Bob wants to send funds to Alice and the trojan controlling Bob's computer replaces Alice's bitcoin address with the one beling to the adversary, things go bad.

One solution would be to create a challenge-response type protocol so that Alice (not Bob) could be sure that the right address (and right amount) are sent to Bob, but that's only part of the solution.

But there are countless other ways you can be fscked and what you should be concerned of if your host is compromised, anyway.

Hi, have you heard of OpenPay? https://bitcointalk.org/index.php?topic=92055.0
How I wish these 3 card related projects can be merged or at least be compatible with each other so that merchants could have only one device for all. (I know this project is not aimed on customer <=> merchant transactions)
Don't take me wrong, I love diversity and competition, but what we need now is single product that can be used by masses.

What I understand from OpenPay is that it targets traditional EMV, which is a totally different beast.

SmartCardWallet is a simple beast, targeting a simple problem, with a simple solution.

You're right it does target EMV compatible cards.  Still I'd like to use the Smartcard wallet as a jumping off point when we start the move to EMV and I invite you to join our project to help get it going.  Seems like you know your stuff, we could use someone like you on the smartcard side of things.

What 3 card related projects?  I agree diversity is good, but no use re-inventing the wheel either.  If I can find a way to make OpenPay more compatible with other projects I consider that a win/win, just let me know.  Send me a PM (sorry to the OP for the thread hijack)
