Your posting doesn't make sense. Why would an incorrect PIN entry put you at risk?

If the (potential) muggers have one of these devices, they can check (at
the time of the mugging) that the cardholder has told them (under
duress) the correct PIN.

Any half-way decent system would defeat this - there's no difficulty designing a system that acknowledges a correct PIN for normal use, plus a second one for use under duress that is accepted, but rings alarm bells at the bank. The muggers could then find the account locked down aftre using an apparently correct PIN.
