If your child goes missing, you want to be able to show authorities current photos quickly, provide information such as the child’s height and weight and get guidance about what to do. Now, thanks to the FBI, there’s an app for that.

The FBI has launched a free iPhone application called Child ID. Parents can store photos and physical identifiers about their children in the application, so it’s easily accessible if needed. The app also lets parents e-mail that information to authorities.
