This attack doesn’t work with smart cards that basically do nothing but act as a HSM. The MITM attack works with a loophole in some EMV cards because the card isn’t signing a transaction request but just saying “PIN is good!” If your card holds a private key and won’t sign anything without also being fed a correct PIN you’d need a proper exploit of the application on the card to defeat it.
