The NFC WLC is a wireless charging technology for low-power compact devices, such as wireless earbuds, smart rings, digital stylus pens, and other consumer products at a power transfer rate of one watt or above. Operating at 13.56 MHz, the technology ensures efficient wireless charging with small size and low-cost printed antennas and effectively uses single antenna to handle both communication and charging, which simplifies system complexity and reduces space requirement space requirement. This transformative technology allows device manufacturers and solution providers to design smaller, lighter and more cost-effective wireless products.
