Collaborative technology to allow smartphones to charge their pens wirelessly via NFC
Smartphones don’t come with stylus pens very often. This is not necessarily due to a design issue, it is largely due to original equipment manufacturers having trouble charging the stylus – they have to be in contact with the device to charge the battery. This problem could find a solution very soon – a memorandum of understanding between the Universal Stylus Initiative (USI) and the NFC Forum has sparked new hope.
This collaboration plans to allow USI members to integrate the NFC Forum’s Near Field Communication (NFC) Wireless Charging Specification (WLC) into their products. WLC integration will allow USI styluses to charge wirelessly with your mobile computing devices, smartphones, and NFC charging devices.
The charging standard allows charging speeds of up to one watt, so digital pens will be powered at a speed of one watt. According to the official press release, “WLC enables a single antenna on an NFC-enabled device to manage communications and load.” This makes it easy and convenient to charge low-power IoT devices.
This means that the technology can be equally useful for charging low-power devices, including fitness trackers, smart watches, and wireless earbuds, to name a few. According to the statement, the USI solution will open up the possibility of having a stylus designed for multiple touch devices.
