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.

what is the GP key ?

Post by glassMan » Fri Nov 13, 2015 3:59 am

I want to develop and debug my own applet using A40CR Card – I will be both the GP Issuer and the Applet Developer.
Is there any keys I need from you to help me manage (unlock/lock) the card?

Our default GP Key is 40~4F, after authentication with gp key,
you could just use set status commands to lock/unlock card.
