RFID is kind of scary. It's in our passports now, allowing people to skim info from us in airports. Companies are gonna start sticking them in employee badges, allowing them to be tracked throughout a building. And now you can get an RFID tattoo permanently making you trackable by anyone who's so inclined.
This update to the always-creepy barcode tattoo will allow your "signal" to be picked up from up to a meter away. Currently researchers at Somark Innovations have gotten their special ink working on cows, rats, and mice, and you know that we're next. Just remember this when you join the army and they want you to get a tattoo for "solidarity." And tracking, big brother. Yikes.
