After a first look, I suspect their cash rely on some online server to prevent double-spending? (With Brands' system (without the "observer" extension), double spending is also detected at the time coins are deposited at the bank. But then it's possible to distinguish between the case of the same coin being used twice in the payment protocol, which is the payer's fault, and the coin info somehow duplicated between payment and deposit, which the payer has no control over).
