If you've ever been to a big museum, or theme park or zoo with a pack of kids, you know the biggest fear is losing them in some of that massive real estate and crowds. Enter TraKid! This idea was born out of NCSU and I've been fortunate enough to see them progress from a simple tracker that kids wear to now the product offers an interactive set of games (think treasure hunt type stuff) that keep kids engaged and excited about the park, but also give parents piece of mind that if they lose sight of their kids, they will be able to find them quickly.
