Re: Two words.
Some may call me a paranoid conspiracist nutcase for suggesting that this is a pilot for a larger scheme (indeed, some have in the last hour or so), but consider the alternative explanation:
That the Powers That Be, believe that attendees of a major music festival are more likely to be criminals, untrustworthy or international terrorists than any other section of the population. It seems to them that its a good idea to surveil this very specific cross section of the community, for whatever reason, and to prevent them using cash in the cause of crime reduction.
Personally, I'm not sure which explanation is worse.
