NFC charging


The organization responsible for the NFC (Zero Range Communication) standard has announced the approval of a new standard.

which will allow the charging of small devices using any larger device, as long as they both support the NFC standard.

The change was made after the company’s board of directors, which includes representatives from ten companies. – including Apple, Google, Qualcomm, and Sony – approved the proposal to add wireless charging capability.

Technical stuff?

The proposal in question, released last year, relies on NFC coils to transfer energy at 250, 500, 750, or 1,000 MW (ie up to a single watt) between a charging device and a charging device. This is in parallel with the transfer of information between them.

The device, which was named WLC (Wireless Charging’s acronym), is based on the fact that NFC transmits electricity wirelessly from the day of its existence.

For example, multi-line cards, which have no battery, work when they bring them to the reader that sends them electromagnetic waves that are powerful enough to “activate” them.

Is it working?

Wireless charging support as part of the NFC facility will allow manufacturers to save the installation of dedicated components for this use, ensuring that any relatively large battery device.

from a cell phone, through a laptop to a TV or home speaker – can charge any smaller device – from a smartwatch, through a Bluetooth headset (Small or large) and up to a tiny IoT sensor that requires charging once a month or year, regardless of the companies that make each device.

This is in contrast to today’s situation, where wireless charging of small devices by larger devices is only possible on flag models such as Samsung Galaxy S10 and Galaxy S20 series (Samsung) or W30i P30 and Mate 20 Pro devices (Huawei) And is based on dedicated technologies that do not fit any device.

“Changing charging”

Koichi Tagawa, forum president and representative of the Japanese printing giant DNP, said:

“Wireless charging in NFC is a significant change because it changes the way we design and manages small. battery-powered devices, and eliminating connections and cables allows smaller devices to be created. And hermetic atoms. “
