Get 0x6A86 when selecting MF

Post by chico0609 » Mon Dec 28, 2015 10:09 pm

From description of SELECT command in ISO7816-4, the following APDU command is used to select Master file.

Code: Select all

00 A4 00 00 02 3F 00


But when I send this APDU to select MF, it returns 6A86.

<<00 A4 00 00 02 3F 00
>>6A 86

I look up the meaning of this status word, it means "Incorrect parameters".


Does this mean my card is not compliant with ISO7816-4? How can I select MF in my card?

IMO, your card is ISO 7816 compliant. And the selection method depends on vendor, you can directly ask your vendor about supported selection methods. or check ATR to know which methods are supported.
Onward...
