What is my physical ticket into the event?

The 2018 Reebok CrossFit Games will be using high-tech, RFID-enabled wristbands to maximize your CrossFit Games experience. Your wristband serves as your admission ticket to enter the Games fast—with just a quick tap of your wristband—so make sure it's registered ahead of time.

Outside Lands, Coachella, and many other major music festivals have turned to RFID-enabled wristbands to allow attendees to come and go freely between venues. We believe it's a natural fit for the CrossFit Games. 

If you've never used them before it's important you take a few minutes to learn how they work:  https://www.youtube.com/watch?v=ndpICHt5-TA
