1. A Near Field Communication (NFC) device, comprising:
- a memory configured to store a list of application identifiers; and
a controller configured to;
determine whether an amount of power available to the NFC device is sufficient for the NFC device to execute a first application corresponding to a first application identifier in the list of application identifiers, andtransmit a portion of the list of application identifiers,wherein the portion of the list of application identifiers includes the first application identifier responsive to a determination that the amount of power available to the NFC device is sufficient for the NFC device to execute the first application, andwherein the portion of the list of application identifiers does not include the first application identifier responsive to a determination that the amount of power available to the NFC device is insufficient for the NFC device to execute the first application.

Abstract
Embodiments of the present invention provide systems and methods for NFC secure application support when an NFC device is executing in a battery-off or battery-low mode. In such a case, the NFC device may have enough power to execute some applications (e.g., read-only applications) but not enough power to execute others (e.g., applications that require data to be written). Embodiments of the present invention enable these lower-power applications to be executed by the NFC device even when a host communications device has no battery power.
