Collaboration Aims To Wirelessly Charge Active Styluses Using Mobile Devices

The NFC Forum and the Universal Stylus Initiative (USI) announced the signing of a Memorandum of Understanding today that points out a collaboration plan to allow USI members to integrate the NFC Forum’s Near Field Communications (NFC) Wireless Charging Specification (WLC) in their products and to verify standards compliance by utilizing the NFC Forum Certification Program.

The integration of WLC will allow rechargeable USI styluses to be wirelessly charged with a smartphone, mobile computing device or other NFC charging device at a power transfer rate of up to one watt.   

The WLC enables a single antenna in an NFC-enabled device to manage both communications and charging. This solution makes it easier and more convenient to charge low-power IoT devices such as smart watches, fitness trackers, wireless earbuds, and other consumer devices like active styluses. The NFC communication technology also allows for setup and configuration of the active stylus while it is being charged.
