The Universal Stylus Initiative (USI) and NFC Forum have announced that they will collaborate on a project to develop a new kind of charging for those mobile devices that come equipped with their own digital pens. Doing so via NFC might mean that the stylus in question could share data with its paired phone or tablet and power up at the same time.

lmao! Charging is not an issue compared to the sore lack of Ntrig and Wacom uptake! The screens need to even support a stylus before any of this and the vast majority simply don't!
Galaxy note devices almost all use wacom emr, which doesn't require powered styluses. This is useless for them anyway.
Notebookcheck does a lot of really good technical review of devices, but it seems a lot of it's writers (and tech media in general) doesn't understand the differences between pen tech.
