[SOLVED] Why I can't select MF?

Why I can't select MF?

I have a JCOP card (CJ3A080). This is output of OpenSC-Tool list files command :

C:\>opensc-tool -a -c jcop -f -v
Using reader with a card: ACS CCID USB Reader 0

Question 1: What is these zero bytes? Is it the EEPROM? if so, why it is just 128 Byte (While my card has a 80KB EEPROM)?

Question 2: What is the meaning of the elements in the below line?

select[NONE] lock[NEVR] delete[NEVR] create[NEVR] rehab[N/A] inval[N/A] list[NON
E]

Question 2: As I understand from the output, There must be a DF with 3F00 as its AID, right? So why I can't SELECT it?

C:\>opensc-tool -s 00a40400023f00

Note that I think this is a Un-Fused Card(Not Personalized) --> Look Here

Update 1:

I tested some other different cards (Even some memory cards) with the same above commands. Output is the same above output and just ATR changed! It this output correct and reliable?

Update 2:

When I list installed drivers, this is output :

C:\>

My card is a JCOP card. And I can see JCOP in the above list. But when I use -n parameter It response with Unsupported Card!

C:\>opensc-tool -n
Using reader with a card: ACS CCID USB Reader 0
Unsupported card

Solution

Maybe this card is not supported by OpenSC

Check the SupportedHardware list. Verify it with opensc-tool --name to see if some driver knows how to handle your card.

The expected result of the command is a line with a card driver name.
