Re: Can someone give me a walk thru on how to change the ATR Please.

Hey guy,

If you have already got the script, just run the script or send the command one by one.

Maybe, you can describe your problem more detailed, then I can give you some clues.

Re: How to get IC serial number from java card

Select the card manager and then send the below APDU to the card

init update
CLA INS P1 P2 Lc Data Le
>> 80 50 00 00 08 2021222324252627 00

Then bytes responseAPDU[4] - responseAPDU[7] are the serial number.

Re: An issue with the verification of ECDSA

Just cut your applet to a small applet which only includes ECC function. Of course, make sure that this small applet can run w/o any problem.

Re: change Java Card Kit version in Eclipse IDE

I have also been trying to change Java Card Kit version in Eclipse IDE due to the applet compiling request, but failed.

Now there is a workaround but not intelligent. I will new a project and reselect the the java card version and then compile.

Re: Cached PIN in JavaCard

Are you sure you want to do One time PIN?
"One time PIN" sounds like you are talking about an OTP (one time password). Generating these is a complex problem.
