Power loss occurs under one of the following conditions:

• The card is withdrawn from the CAD.

• When operating in contactless-only mode, the card loses carrier energy from the radio frequency (RF) field and enters the POWER OFF state as defined in the ISO 14443 Specification Parts 1-4.

• When operating in contactless-only mode, the card receives a Supervisory block (S-block) DESELECT command and enters the HALT state as defined in the ISO 14443 Specification Parts 1-4.

• A mechanical or electrical failure occurs on the card.

When power is reapplied to the card and on card reset (warm or cold) the Java Card RE shall ensure that:

• Transient data is reset to the default value.

• The transaction in progress, if any, when power was lost (or reset occurred) is aborted.

• All applet instances that were active when power was lost (or reset occurred) become implicitly deselected. In this case the deselect method is not called.

• If the Java Card RE implements default applet selection (see Section 4.1, Default Applets), the default applet is selected as the active applet instance for the basic logical channel (channel 0), and the default applet's select method is called. Otherwise, the Java Card RE sets its state to indicate that no applet is active on the basic logical channel.
