Thanks for the reply,
ChangeKey never executed, since very first authentication of PICC is failing.
Just one quick question
Keeping master key as default 2k3des, I can create applications under it with AES128 key?
Also will it be tamper proof for application data? External world should not be able to access our application data, even if PICC is 2k3des key.
Can you please throw some insights on the same.
Want to try this in new card, hoping we don't face the earlier problem.
