Abstract
Systems, methods, and computer-readable media for managing near field communications during a low power express mode of an electronic device are provided that may make credentials of a near field communication (“NFC”) component appropriately secure and appropriately accessible while also limiting the power consumption of the NFC component and of other components of the electronic device.
Claims20
A method comprising:
- designating a credential on an electronic device as an initial credential for use in a low power mode of the electronic device;
- in response to the designating, setting a status of a low power mode flag of a power management unit of the electronic device to a first status;
- and
- after the setting the status of the low power mode flag, detecting a low power mode initiation event;
- in response to detecting the low power mode initiation event:
- determining the status of the low power mode flag of the power management unit of the electronic device to be the first status or a second status;
- and
- responsive to determining that the status of the low power mode flag is set to the first status, transitioning a near field communication component from operating in a full power mode to operating in a low power mode, or
- responsive to determining that the status of the low power mode flag is set to the second status, transitioning the near field communication component from operating in the full power mode to operating in an off mode.
An electronic device comprising:
- a memory;
- a power management unit;
- a near field communication component;
- and
- at least one processor configured to:
- designate a credential on the electronic device as an initial credential for use in a low power mode of the electronic device;
- in response to the designate, set a status of a low power mode flag of the power management unit of the electronic device to a first status;
- and
- after the status of the low power mode flag is set, in response to detection of a low power mode initiation event:
- determine the status of the low power mode flag of the power management unit of the electronic device;
- and
- responsive a determination that the status of the low power mode flag is set to the first status, transition the near field communication component from operating in a full power mode to operating in a low power mode.
A non-transitory machine-readable medium comprising instructions that, when executed by one or more processors, causes the one or more processors to perform operations comprising:
- designating a credential on an electronic device as an initial credential for use in a low power mode of the electronic device;
- in response to the designating, setting a status of a low power mode flag of a power management unit of the electronic device to a first status;
- and
- after the setting the status of the low power mode flag, in response to detecting a low power mode initiation event:
- determining the status of the low power mode flag of the power management unit of the electronic device;
- and
- responsive to determining that the status of the low power mode flag is set to the first status, transitioning a near field communication component from operating in a full power mode to operating in the low power mode.
