The same NFC antenna will be used to transmit information and power.

The NFC Forum, an international standardization company for Near Field Communication (NFC) technology, has approved the Wireless Charging Specification (WLC). This specification allows you to wirelessly charge small consumer and battery-powered IoT devices using your smartphone or another NFC-enabled device. The transmitted power can reach 1 W.

NFC Forum Approves Wireless Charging Specification

The WLC provides for the use of the same antenna in an NFC-enabled device for communication and charging. Allegedly, this solution simplifies the charging of low-power devices such as smartwatches, fitness trackers, wireless headphones, digital pens, and other consumer devices.

Last year, the WLC specification was published as a candidate for standardization, and now the association has accepted it as the final version, ready for implementation on the market.

The specification uses a base frequency of 13.56 MHz and an NFC communication channel to control power transmission. NFC technology allows you to transfer power to the NFC tag to provide connectivity. The WLC specification extends this NFC functionality to provide wireless charging.
