Who are you?

This is something that has gone through my mind many times, You are out on a trail, A long way from anywhere and you have an accident, You have left your wallet with details in your car and you are found unconscious, Who are you, How does that person get in touch with your family, What if you have allergies to meds etc, Last night i was looking through backpacker magazine when i found Road ID, Simple but very effective, basically a bracelet with all your info on it, I ordered one straight away, What i liked about the site was that you could design your bracelet and it showed it then and there, Lots of colors available and not expensive, It could be a life saver
