I was actually the third person down the tunnel, and the first person into the actual building, when they opened their doors. When you get their, you get a "badge" to wear around your neck that has an RFID chip in that when you first "check in, you basically set up your "profile (why I was able to get in first), like select your favorite team. As you walk up to displays, specifics including GA Tech will pop up.
When you get upstairs to the actual HoF, you will get to kiosks that allow you to select teams, players/coaches, and specifics on them, etc., and it can start on you RDID chip.
If you plan on going more than once, I suggest you purchase the "VIP" pass (annual passes) as they'll be much less expensive over the long haul.
