Using the pass was easy, too; you just tap it and confirm that you want to use it that day. There's a countdown timer that lets you know how long you have use it, once activated — it was about 18 hours for me, and you can use it multiple times that day if for some reason you get the urge for a two-a-day. You just tap to view the pass and show it to the gym representative when you walk in.
There's a Zeamo customer support number on the pass in case you run into any trouble, but it was fine for me. I activated my pass right outside the door and showed it to the gym employee without any issues, and I was on my way to start a workout like any other gym member.
