Each command that appears on the card command interface SHALL be implemented by a card application that is resident on the ICC. The card command enables operations on and with the data objects to which the card application has access.

Each card application SHALL have a globally unique name called its Application Identifier (AID) [ISO7816 , Part 4]. Except for the default applications, access to the card commands and data objects of a card application SHALL be gained by selecting the card application using its application identifier. 1

1 Access to the default application, its commands, and its objects occurs immediately after a warm or cold card reset without an explicit SELECT command. The PIX of the AID SHALL contain an encoding of the version of the card application. The AID of the PIV Card Application is defined in Part 1.

The card application whose commands are currently being used is called the currently selected application .
