The NFC Forum has announced an update for the NFC (Near Field Communication) standard with the addition of the Wireless Charging Specification (WLC).
The new specifications makes it possible to wirelessly charge small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt.
This will improve the user experience for the two billion consumers and businesses using smartphones and other NFC-enabled devices.
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, digital pens and other consumer devices.
The WLC was published last year as a Candidate Specification and after a careful validation process, the NFC Forum is now able to publish this specification as an adopted Technical Specification, ready for implementation in the market.

NFC wireless charging is truly transformative because it changes the way we design and interact with small, battery-powered devices as the elimination of plugs and cords enables the creation of smaller, hermetically-sealed devices.
