HOUSTON — NFL and law enforcement officials say fans can tell if they are buying real Super Bowl tickets by checking for the heat-sensitive logos.
On the front of each ticket is a full polymer graphic that is raised and the back features a true color security label with Houston’s skyline and the Super Bowl logo. The final security feature is a graphic on the lower portion of the back of each ticket which is printed with thermochromic ink. The HTX logo and the NRG Stadium image will fade when heat is applied and will return when the heat source is removed.
