Mobile’s NFC creates a short-range electromagnetic field that is primarily used for transferring information such as payments or pairing Bluetooth devices, but can also be used for charge devices wirelessly. NFC Forum already presented the official specification for this 1W wireless charging in May.
It is a very limited power -a standard mobile today starts at 10W and the bells of 200W are already ringing for next year- so its use is limited to charging small accessories such as headphones, watches or other small devices. . Some that have joined the bandwagon are the stylus, and that is because NFC Forum and USI, the universal stylus initiative, have signed a collaboration agreement that allows its members to incorporate NFC wireless charging into their stylus.
Standard stylus charging via NFC
The NFC Forum and Universal Stylus Initiative associations today announced a collaboration agreement whereby members of the latter can integrate the NFC wireless charging specification into your products.
The Universal Stylus Initiative, or ISU, is an organization that seeks to define interoperability standards between active stylus (which have their own battery) and devices with touch screens such as phones or tablets. Among its members are Google, Intel, Lenovo, Dell, Sharp, Wacom, Samsung or HP, to name a few.
This collaboration agreement will allow USI members to incorporate the wireless charging standard WLC (Wireless Charging Specification) of NFC, by which can charge the stylus with a maximum power of 1WNot much to charge a mobile, but enough for this type of device.
Hopefully this news will be a Universal stylus charging system regardless of the brand of stylus or mobileAlthough it remains to be seen which NFC devices will launch with support for the WLC standard for wireless charging.
