Japan’s Hitachi Information Systems on Thursday announced a new kind of concert entry system that utilizes a tiny mu-chip smart tag to prevent the forging and scalping of tickets. The mu-chip is a tiny Radio Frequency Identification chip made by Hitachi. Hitachi Information Systems already utilizes the mu-chip for its Chipin series of systems to manage the movement of people in and out of rooms, but the majority of these are used in offices.
