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.
