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.

Problem with my J2A040 Jcop 40k java card.

Post by Yokoshimoto » Thu Dec 23, 2021 6:41 pm

Hello,
My problem is as follows, when trying to format the card something goes wrong. I want to format ATR in my J2A040 card, but I do not know what to do when this error pops up, I tried everything but THE ATR still remains the same.

If i try to format card in pyApdutool the RECV is 6A 82.

What i can do with this?
