NFC forum specification adds support for extra-small antennas for NFC wireless charging • NFCW

The NFC Forum has approved and adopted a specification that expands the range of small battery-powered consumer and Internet of Things (IoT) devices that can be charged wirelessly using an NFC smartphone or other compatible device. NFC.

The Wireless Charging Specification (WLC) 2.0 follows the WLC 1.0 specification adopted in May 2020 by allowing a single antenna in an NFC-enabled device to handle both communications and load, but adds support for “sizes”. even smaller ‘antennae’ such as those used in wireless headphones.

“This is a transformation for device manufacturers and solution providers as it enables the design of smaller, lighter and more affordable products,” the forum said.

“In addition, the NFC Forum believes that the majority of mobile phones are interoperable with the extra-small antennas covered by WLC 2.0. “

“More than 60m of wireless headphones were sold in the first quarter of 2021 worldwide. These and many other consumer products operate with rechargeable batteries, and the NFC Forum’s Wireless Charging Technical Specification 2.0 is a simple and convenient method of keeping everything charged, ”adds NFC Forum Executive Director Mike McCamon.

“This specification will also further improve the user experience for the two billion consumers and businesses using smartphones and other connected products.

“This is part of a global trend towards the creation and proliferation of smaller rechargeable devices and will allow the majority of smartphones and other NFC-enabled devices to communicate with and charge these products. “
