Payment systems and methods for providing a wireless power charge are disclosed. In one exemplary implementation, a system includes a wireless charger that is used to provide a power charge to a wirelessly chargeable device. Prior to providing the power charge to the wirelessly chargeable device, the wireless charger obtains payment-related information from the wirelessly chargeable device using near field communications (NFC), and transmits this payment-related information to a payment center via a network such as the Internet. The payment center uses the information to either deny or authorize the power charge operation. If authorized, an authorization indication is provided to the wireless charger via the network, and the wireless charger then wirelessly transmits a suitable power charge to the wirelessly chargeable device.

Systems and methods pertaining to wireless power transfer are disclosed. Specifically, disclosed herein are calibration procedures that incorporate transmission of a reference power charge from a wireless power charger to permit determination of an optimized receiver circuitry configuration in one or more wirelessly chargeable devices. The result of the calibration procedures may then be used by the wireless charger to assign various frequencies to several wirelessly chargeable devices so as to optimally transfer a steady state power charge at one or more frequencies to the wirelessly chargeable devices.

Systems and methods pertaining to multi-frequency wireless power transfer are disclosed. In one exemplary implementation, a wireless charger is used to generate and transmit two wireless power charges at two different frequencies, using a frequency division multiplexed (FDM) format. A wireless sly chargeable device that is inductively coupled to the wireless charger receives the two wireless power charges in the FDM format and uses the two charges to charge one or more chargeable batteries contained in the wirelessly chargeable device.
