 NXP also stated "Also, the impact of a successful attack depends on the end-to-end system security design of each individual infrastructure and whether diversified keys – recommended by NXP – are being used.If this is the case, a stolen or lost card can be disabled simply by the operator detecting the fraud and blacklisting the card, however this operation assumes that the operator has those mechanisms implemented.This will make it even harder to replicate the attack with a commercial purpose."
