1. A near field communication (NFC) device, comprising:
- a processor;
a battery; and
a memory storing instructions, execution of which cause the processor to;
check a power level of the battery to determine a power mode of the NFC device,receive a request for an application identifier (AID) from a communications device,access a list of AIDs,select a first AID in the list of AIDs corresponding to a first financial application as the AID if the NFC device is operating in a full power mode,select a second AID in the list of AIDs corresponding to a second financial application as the AID if the NFC device is operating in a battery off mode, andtransmit the AID to the communications device.

Abstract
Systems and methods for providing secure application support for NFC devices in both battery on and battery off modes are provided. A first application that requires available host battery supply and a second application that does not require available host battery supply are loaded onto a mobile device. When the second application is enabled, the reader requests user input on a POS device. The first application is enabled when host battery supply is available, and the second application is enabled when no host battery supply is available.

11. A method, comprising:
-
checking, using a processor, a power level of a battery to determine a power mode of a near field communication (NFC) device; receiving, using the processor, a request for an application identifier (AID) from a second NFC device; accessing, using the processor, a list of AIDs; selecting, using the processor, a first AID in the list of AIDs corresponding to a first financial application as the AID if the NFC device is operating in a first power mode; selecting, using the processor, a second AID in the list of AIDs corresponding to a second financial application as the AID if the NFC device is operating in a second power mode; and transmitting, using the processor, the AID to the second NFC device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
