Every year golf enthusiasts flock to Augusta, Georgia for The Masters Tournament, the sport’s greatest spectacle. The Masters is one of four major championships in professional golf, which means it’s a pretty big deal. Large sporting events such as this often require strong security because of the huge crowds they draw. Event IDs help to maintain a certain level of order by quickly identifying who belongs where. These cards are often color coded to distinguish spectators from members of the press, athletes, officials, and volunteers.

Here are a couple photos showing off the event passes on display at The Masters:


As you can see, there’s another cool thing that happens with these event IDs; people collect them as souvenirs. It’s not just an entry pass, but also something that people can hold onto as a memento of their time at the event.
