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.

JC30M48CR wrong ATR keeps getting written

Post by SAPPHIRE » Tue Oct 24, 2017 1:39 am

Javacardos team please respond to my email.

I bought some JC30M48CR cards from your store (with the promise that I'll be able to change the ATR)
You sent me the script to change the ATR which I followed carefully well as instructed.

But when I use pyApdutool to try and change the ATR....I keep getting wrong ATR as the final result.
The final ATR written is not my desired ATR.
I sent the right HIST. BYTES, the right COLD and WARM ATR
I set the command perfectly as instructed and I sent the command to the card using the binary option of the apdu tab in the pyApdutool.

I sent you guys an email concerning this but it seems my email is getting ignored.

How is it possible that the ATR is being written BUT the wrong ATR is what is being written to the card?
Its been over 4 days now please respond to my email and help me sort this please.

Anyone else here wants to help me?
