I was thinking to use a reader on my phone to get a NFC tag that will give an input on my game to use it for an action.

Just  like the seventh console generation's game (eg. Skylander, Disney Infinity).

The problem is that, while reaserching some API on UnityForum or other websites  I couldn't find anything helpfull for Windows.

Feel Free to give some suggestion for everyone that will search a content like this in the future.
