Guided Access is an Apple security feature that keeps anyone from leaving the app currently in use. With Simple Booth, it locks participants into the booth flow, from "Tap to Start" through photo editing and sharing and back to "Tap to Start." This helps protect both your iPad's sensitive information and your booth settings.
Turning on Guided Access
You need to set up Guided Access, including choosing a passcode, before you can use it. After that, you can turn it on once your booth is launched. Learn more in Apple's Guided Access guide.
