Get Card Manager ID

Post by Methen » Thu Dec 22, 2016 12:00 am

I tried to get Card Manager ID by sending SELECT APDU command without AID >>00a4040000, but I got nothing but 6E00.
Is there something wrong with APDU command I sent?

There probably is something wrong with your card.
Generally speaking, SELECT command with no AID provided will select the Card Manager and the Card Manager AID should be returned in the response.

Using GET STATUS command can also get Card Manager AID.

GET STATUS needs authentication to the Card Manager first. If the Card Manager is not the default selectable applet, you can't use this.
