The free FBI Child ID app provides a convenient place to electronically store photos and vital information about your child so that it's literally right at hand if your child goes missing. You can show the pictures and provide physical identifiers such as height and weight to security or police officers on the spot. Using a special tab on the app, you can also quickly and easily e-mail the information to authorities with a few clicks.
The app also includes tips on keeping children safe as well as specific guidance on what to do in those first few crucial hours after a child goes missing.
