How to unlock my card

Post by crizom » Wed Jul 06, 2016 6:01 am

Pls Help! I bought some javacards to do my own research. And I tried to lock card many times and finally it's successful. Now I can not select ISD and other applet operations. :cry: How can I make my card back to "default set"? I want my card backto the state when I received the card. Pls help me!

Thanks in advance!

From the Card Life Cycle State Transitions diagram in GP spec, if your card state is CARD_LOCKED, you can just reverse card state to SECURED. Then everything will be back to normal.
