It's a scenario that many parents know all too well.
You're shopping at the store when suddenly your child disappears, but what happens when you can't find them?
Well, the FBI has released a Child ID app for just such a situation.
The mobile app provides a place to store photos and vital information about your child such as height and weight.
There's even a special tab to send authorities the information quickly.
Right now, the app is only available for iPhones.
It can be downloaded for free from the app store on I-tunes.
