We describe the implementation of a distributed proximity detection firmware for the OpenBeacon RFID platform. We report on experiments performed during conference gatherings, where the new feature of proximity detection was used to mine and expose patterns of social contact. We discuss some properties of the networks of social contact, and show how these networks can be analyzed, visualized, and used to infer the underlying social structure.
