Four RFID readers made by Alien Technology were placed in the museum's reception area so that people's movements throughout the room could be tracked. This green reader was located by the bar at the front door. People whose RFID history was mostly green or blue spent most of the time at the bar. Red indicated dancing, and yellow talking.

Another member of the project, Berkeley lecturer David Ross, is not pictured.
Visitors of the MoMA's reception on Thursday evening were given a RFID tag to wear. Each tag was implanted with a unique number that could be tracked when it came within range of one of the RFID tag readers.
