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.

Disabling Issuer Security Domain

Post by openxdev » Sun Nov 21, 2021 11:44 am

I have a few sample java cards (JCOP4 P71). My questions:
1. For my application, no loading or deletion of applet is allowed once the applet is loaded into the card. Is it a common practice to disable the selection of ISD once applet has been loaded into the card ? Is changing the ISD keyset sufficient ?

2. What is the command to disable ISD selection ? Is this equivalent to changing the ISD state from SECURED to CARD_LOCKED ?
