What does “Security condition not satisfied” response APDU mean?

Question

I am playing with my NFC card with Android NFC API. I am stuck at this APDU response: Security condition not satisfied (SW1=69, SW2=82).

Can anyone expl

Answer 1

The status word 69 82 ("Security status not satisfied") typically means that your current authentication state is insufficient to access a certain resource on the card. E.g. if you get that in response to an UPDATE BINARY command, you might not have permission to change the content of the file. Similarly, if you get that in response to a READ BINARY command, you might not have permission to read binary data (random access) from the file.
