card returns "6A 88" after sending Get Data command

Post by kineri » Thu Dec 10, 2015 3:57 am

I have a white java card. And I want to get some card information from the card. So I send GET DATA command(80 CA P1 P2 00) to card via pyApdutool.
I set P1 & P2 value as follows:
• Tag '42': Issuer Identification Number
• Tag '45': Card Image Number
• Tag '66': Card Data
• Tag 'E0': Key Information Template
• Tag 'C1': Sequence Counter of the default Key Version Number

I select the card manager first and then send the APDU commands as "Basic APDU" in pyApdutool showed.



From the figure, we can see that the card returned "6A 88" for tag "42", "45", "66".
Can I think that my card didn't have these corresponding information? Or did I miss something when sending these three APDU commands , so it return"6A 88".

For these data you mentioned, probably ISD doesn't do the personalized operation.

In this situation, you can store these data(s) to the card using the STORE DATA command. See GlobalPlatform specification for more details.
sense and simplicity
