NFC charging may mean that your next phone charges your earbuds or smartwatch wirelessly. NFC or Near Field Communication is a wireless technology present in many phones that allows them to connect or interact with other devices, such as pairing a Bluetooth speaker by tapping on their phone. The NFC Forum, which is responsible for the technology, has now unveiled a new standard, the Wireless Charging Specification (WLC), which will allow smartphones or chargers with NFC to power devices at 1W.

Until now, smartphone manufacturers have had to develop proprietary technology for their phones to allow ‘allow reverse wireless charging’. With the development of WLC, it is likely to become a much more standardized part of smartphones going forward.

According to the press release deployment of On the NFC Forum website, the association has approved and adopted the WLC, which will allow devices with NFC to charge other small “battery-powered consumer and IoT devices” of up to 1W. While this charging speed may not sound impressive, it is sufficient to charge smartwatches, wireless ear buds, and other devices.

Specifically, this WLC technique was published as a candidate specification last year and after a verification process, it has been published as an adopted technical specification and is ready for market implementation. The press release stated that there are an estimated 36 billion IoT devices in use and that many of them will be able to charge wirelessly using WLC. As of now, there is no timeline for this technology to come to market.

how it works

WLC enables a single antenna to manage both communication and charging in an NFC-enabled device. This specification uses a 13.56 MHz base frequency and uses an NFC link to control power transfer. To provide a continuous carrier signal, NFC allows the transfer of power to the NFC tag for communication. The WLC uses this functionality to enable wireless charging at 1W.

what does this mean?

Theoretically, it can allow any phone with NFC to charge any small device that allows wireless charging. This means that other devices, like Samsung’s PowerShare, will also be able to “reverse wireless charge” such as smartwatches, True Wireless earbud cases, and many other devices.

The Chairman of the NFC Forum, Koichi Tagawa, said, “NFC wireless charging is truly transformational because it changes the way we design and interact, eliminating plugs and cords as small, battery-powered devices.”
