Smartphone Emergency Information

Both iOS (Apple) and Android (Google) phones provide a way for anyone with your phone to get critical medical information or dial an emergency contact without unlocking the phone, but you have to configure it now if you want it to be used later.  Most commonly this will be used to allow someone that has found your lost phone to return it, but can be a life-saver if you're not conscious during a medical emergency.  Don't hesitate, do it now.
