There are two ways to select an applet instance in the Java Card platform: with a MANAGE CHANNEL OPEN command ( Section 4.5.1, Applet Selection with MANAGE CHANNEL OPEN), or with a SELECT FILE command ( Section 4.5.2, Applet Selection with SELECT FILE).

The Java Card RE shall guarantee that an applet that is designed to run on any logical channel can be selected on any of the available logical channels on the card. The resources accessed by the applet instance must be the same, irrespective of the logical channel on which it is selected.
