IV system

An IV system (or Identify and Value) was a device that could scan objects, search for them in a massive database and state their value. Solomon's ship had an IV system. When it scanned the Eleventh Doctor, it was unable to find any information on him, (TV: Dinosaurs on a Spaceship) as the Doctor had been removing records of him from history. (TV: The Angels Take Manhattan) After scanning the rest of the Silurian Ark, Solomon also found Nefertiti. (TV: Dinosaurs on a Spaceship)
