First Claim
Patent Images
1. A machine-implemented method of charging a receiver, the method comprising the steps of:
- harvesting power from an NFC signal by a receiver having a GPS device;
utilizing the harvested power to power the receiver to perform an authentication procedure with a source of the NFC signal;
transmitting a secure communication and GPS location data to a server via a mobile network for authentication by the server of information included in the secure communication; and
in response to authentication of the information included in the secure communication, receiving charging from the source of the NFC signal.

Abstract
A wireless charging apparatus and method utilizing a secure element is disclosed. Illustratively, a receiver containing a secure element securely communicates with a charging pad also equipped with a secure element. The communication can be used to establish the identity of the receiver and facilitate billing for the wireless charging. The charging pad may further communicate in a secure manner with a server to authenticate the identity and other information about the receiver before providing wireless charging. Direct communication between the receiver and server is also contemplated.
