NFC-Enabled Wireless Charging

Abstract

This paper summarizes the results of our concept development for NFC-enabled wireless charging - i.e., an add-on to the existing NFC operating modes that implements charging power transmission and charging power reception with associated control functionality. When compared to dedicated wireless charging solutions, integration of NFC and wireless charging into the same implementation will entail more compact and cost-efficient charging interfaces for portable devices, a more pervasive charger infrastructure in future with reduced costs, and the possibility of integrating NFC-based services into charging applications. We propose to the NFC community a closer investigation of use cases, the business potential, and technical implementation of NFC-enabled charging. This should lead to a road map for its wider adoption, pave the way to its standardization, technology development, and commercial application, and also support enhancement of power transfer capability in other NFC applications alongside wireless charging.
