1. 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.
