OK, reading the article it seems that it is a tattoo that relays voice vibrations to your smartphone.
If I understand that correctly it doesn't have to be the bar code on the back of your neck (like that in the picture... obviously used for shock value).
I wonder it it could be any type of tattoo anywhere on your neck that could pick up vibrations?
"If you think a Bluetooth headset makes you look like a tool, how about replacing it with a … throat tattoo?
That’s right, a throat tattoo. Google-owned Motorola has received a patent for a smartphone-connected system “that comprises an electronic skin tattoo capable of being applied to a throat region of a body.”
According to the patent, which was published last week, the “electronic neck tattoo” connects to a smartphone via a “transceiver” similar to the way a Bluetooth headset, smartwatch, or Google Glass device would pair with a handset. It would have its own power supply and can be outfitted with a microphone, which would allow you to control your phone using only voice commands."
