I was in Europe with my family a couple years ago and my sister got sick. We had some trouble getting her medicine, because the doctors didn't have access to her current medical records. Care Card is the perfect solution, because it will allow everyone to safely and securely travel with an ID card that gives direct access to their medical records.
Insurance companies everywhere would encourage everyone to use Care Card, because the cards will decrease wasteful medical spending and make the insurance companies billions of dollars. I suppose the insurance companies could even be licensed the idea.
Put yourself in the shoes of someone who is allergic to certain medication. Now imagine getting into a car accident and being knocked out. The doctors and EMTs know nothing about you. Wouldn't your prefer that they have the ability to make educated decisions based on your medical records before they come close to operating on you?
