In case of an emergency, every second counts. With Sign4l, you can instantly email or text your child's profile to the proper authorities thereby allowing you to gain valuable time and consequently permitting authorities to treat the emergency much more expeditiously.

Sign4l allows users to store up-to-date images and physical descriptions—such as height, weight, birthmarks, that could help responders in the event of an emergency. The information is stored only on the user’s device—not with one’s mobile provider or law enforcement.
