An electro-tattoo was a type of tattoo whose ink was capable of carrying data. The outlaw tech and tattoo artist Naley Frifa was adept at inking both gang symbols and electro-tattoos. Doctor Chelli Lona Aphra had electro-tattoos on her right arm. She described her tattoos as "intriguing" and refused to answer whether they were a sign of being a daredevil or a "youthful mistake." She eventually came to question if others still got the tattoos.
