Finnish mobile phone developer Nokia has filed for a patent on a magnetic, vibrating tattoo or badge that alerts users when their phones are ringing.
According to the official patent filing, the apparatus would be able to detect a magnetic field and transfer a "perceivable stimulus" to users. The device could notify people about an incoming call, text or dead battery.
That's just cool, and a small step away from one that you plant behind your ear that is sensitive enough to play and capture your voice.
And another reason for a tattoo. Win-win-win.
