Kid Turn In

Before taking a family trip to Disney World in the spring of 2013 with his daughter and nephews, Buckeye Interactive President Brad Griffith prototyped a quick application called Kid Turn In. With the application he would print a temporary tattoo with a QR code that, upon being scanned, would send an alert with the scanner’s location to the adults on the trip. These tattoos were applied to the children in the hopes that if they were to be separated from the group a good samaritan would scan the tattoo (the kids had been instructed to point out the tattoo if they got lost) and the parents would be more quickly reunited with the little one.

Fortunately the Griffiths didn’t end up needing to test it in the field, but the idea was sound. Brad brought the idea into the office where we started developing a new version of the app from the ground up using the Laravel application framework. The application handles finding the scanner’s coordinates, plotting them on a map, and sending email and SMS alerts. Upon registering a child a unique URL (and QR code pointing to that URL) are generated and available for parents to download. Users can also order temporary tattoos or wristbands with their child’s QR code directly from Kid Turn In.
