What is the MixMaster list, and what is it for? Apologies on my newbie status.

You don't need a strong authentication technique

if a stolen card is easy to cancel.

The card's easy to cancel, but the cash ain't. Credit cards are cleared with the issuer. Digital cash with smart cards acting as transaction observers don't need this. The thief need only transfer the cash from the stolen card to his own, just like he does with regular cash.

Even with a weak PIN system for authentication, you can always provide a "duress" PIN, right?

Sounds like a better choice.
