Abstract:
A power receiving apparatus for receiving power transmitted by wireless power transmission from a power transmitting apparatus, comprises a first communication unit for communicating with the power transmitting apparatus, and a second communication unit for performing communication at a speed higher than the first communication unit. The power receiving apparatus determines, by communication via the first communication unit, whether the power transmitting apparatus has a function of transmitting/receiving, via the second communication unit, information for device authentication with the power transmitting apparatus, and enables the second communication unit to execute transmission/reception of the information for the device authentication with the power transmitting apparatus via the second communication unit if it is determined that the power transmitting apparatus has the function and the second communication unit is in a disabled state.
