Belongs to pitch: Knab Part II
Millennials spend way too much. Especially when they are on a festival. That's why Knab is going to help them control their expenses, with the Knab Wristwallet. An existing payment method used on festivals.
(If the screen in a wristband isn't possible, you could use a screenless wristband and put Knab checkpoints at every festivalstage.)
