SmartWater

Greater Manchester Police SmartWater warning sign

SmartWater is a traceable liquid and forensic asset marking system (taggant), applied to items of value to identify thieves, and deter theft. The liquid leaves a unique identifier, whose presence "cannot be easily seen by the naked eye" except under ultraviolet black light.[1]
