A major music festival is a security nightmare with potentially more than 100,000 people coming and going, not to mention drinking and doing who knows what else. You never know who is going to turn up or cause problems.
However, you might be a little concerned with how the festival organizers at the Download Festival at Donington in Leicestershire, England, are handling it.
The first step is RFID wristbands for everyone. To get in, move between festival areas and even pay for food, you need your wristband. Which means the festival organizers can track everything you do.
That's a little worrying, but it makes sense. What doesn't make sense is the second layer of "security" that no one was even supposed to know about.
