Your phone’s NFC will have a new feature: charging other devices wirelessly
The NFC Forum, the global association charged with defining standards for NFC technology, has announced the approval and adoption of the Wireless Charge Specification (WLC). This will allow mobile phones to use their NFC chip to wirelessly charge small devices such as headsets or smart watches.
In case you don’t know what NFC is, it stands for Near Field Communication. It is a high-frequency wireless technology with a very low range of 10 to 15 cm. To support it and enjoy its functions, mobile phones have to include an NFC chip.
Currently, NFC is used for the exchange of information, mainly in payment systems with the mobile phone, but also has other uses, for example for instant synchronization of the smartphone with other wireless devices.
Now, with the new specification announced, your mobile’s NFC will have a new utility and will be able to charge other devices wirelessly.
“The wireless charging specification allows a single antenna on an NFC-enabled device to manage both communications and charging,” explains the NFC Forum in a statement. “This solution makes it easier and more convenient to charge low-powered IoT devices such as smart watches, fitness wristbands, wireless headsets, digital pens and other consumer devices.
The aim of this specification is none other than to make life easier for users, making it possible to use the mobile phone’s NFC to charge small devices and avoid the need to use a different charging cable for each device.
Something that often goes unnoticed, but which is very useful for many users, is the NFC technology of mobile phones. However, there are times when NFC must be deactivated, and we tell you how and why.
However, the wireless charging system that NFC will provide is quite limited in terms of speed. The power transfer rate is 1 W, while the reverse wireless charging systems offered by some smartphones are between 5 and 10 W.
The WLC specification is now ready for implementation, but we have to wait until it reaches the market and know what the requirements are before we can benefit from this new feature.
