Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

unlock the ISD

Post by Aesir » Thu Dec 15, 2016 11:47 pm

I know that each transition from state to state is irreversible except from CARD_ LOCKED to SECURED, only to the ISD.
That is, the Card Life Cycle state transition from SECURED to CARD_LOCKED is reversible.
I tried to LOCK the ISD with the following APDU:
>> 80 F0 80 7F 07 A0 00 00 01 51 00 00

The command was successful but I can not login to the ISD any more. How do I unlock the ISD?

Your card probably enforces secure channel security level C_MAC once the card life cycle reaches the SECURED state.

Continue to send command to select ISD and establish secure channel. Then change card life cycle back to SECURED.

>> 00 A4 04 00..

>> 80 50 00 00..

>> 84 82 01 00..

>> 80 F0 80 0F..
