    abstract     = "In this paper we report our experiences with an exploratory prototype festival-wide social network applying unique {2D} barcodes on wristbands and mobile phones to uniquely identify the festival participants. Experiments were carried out at the CO2PENHAGEN music festival in Denmark. We describe a set of social network applications involving participant profiles, a microblog and images shared on situated displays, and competitions created for the festival and our experiences from initial use of these. The pilot study included 73 participants each creating a unique profile. We found that our novel approach had potential to enable anyone at the festival to participate in the festival-wide social network, as participants did not need any special hardware or mobile client application to be involved. The {2D} barcodes was found to be a feasible low-cost approach for unique participant identification and social network interaction."
