Getting other samples by Paying Freight only
Thanks for the great activity- Getting Free Samples by Paying Freight only. I have got the A40CR and JC30M48CR cards. The cards work fine so far.
Will you hold the same activity with other products, such as ejava token or A22CR card? I am looking forward to these.

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.

flaws in Infineon RSA key generation
Recently, researchers have found flaws in Infineon RSA key generation. I have bought some JC30M48CR cards. Is this card based on Infineon chip? I want to be sure that it’s not using the troubled Infineon RSA key generation code?. Any information is helpful for me. Thanks.

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: Get info in paypass credit card
The Paypass application has blocked the contact interface. So please use a contactless reader to read it.

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: Error 6F00 when generating and verifying a signature
Try to change the sig_buffer to a bigger balue. RSA Signature alone is 128 Bytes.
