An electronic device such as a portable electronic device has wireless power receiving circuitry. A vehicle has a vehicle remote keyless system that transmits beacons. A key receives the beacons and responds with key codes to unlock doors and enable a vehicle ignition in the vehicle. In the presence of wireless power transfer operations there is a risk that wireless power signals will interfere with the reception of the beacons by the key. To ensure that beacons are satisfactorily received, conditions in which there is a risk of interference are detected and corresponding interference mitigation operations are performed.

Systems, methods and apparatus for wireless charging are disclosed. A charging device has multiple transmitting coils, a driver circuit configured to provide a charging current to the resonant circuit, and a controller configured to provide a charging current to the transmitting coils. The apparatus includes a resonant circuit that includes one or more transmitting coils and a driver circuit configured to provide a charging current to the plurality of transmitting coils. The controller may be configured to provide a charging current to the resonant circuit when a receiving device is present on a surface of the wireless charging device, determine that an interrogation signal is being transmitted by a keyless entry system, suspend the charging current for a period of time, determine that the interrogation signal has ceased while the charging current is suspended, and restore the charging current to the resonant circuit after determining cessation of the interrogation signal.

An information processing device relates to a predetermined service provided to a user by allowing a worker to temporarily access a vehicle cabin including a trunk of a vehicle used by the user. The information processing device includes a processor. The processor is configured to determine whether the worker relating to a service provider of the service has unlocked a door of the vehicle using key information for unlocking the door, the door accessing the vehicle cabin of the vehicle, and notify the user of a warning or activate an alarm device of the vehicle, in a case where the processor determines that the door has been unlocked and in a case where the processor determines that a state in which the door of the vehicle is not locked continues after a predetermined time has elapsed from unlocking of the door.
