> I'm interested to know how adding a QR code for this information is better than putting the information itself on the helmet
I'm interested to know what emergency responders would have a clue what a random QR code would be, twig that it has your medical info on it, and figure out how to read it. In less than a 3-day required course.
Most of the American medical personnel have difficulties responding to a text. All the doctors and nurses are complete technical idiots and PROUD OF IT thankyouverymuch.
Computer? Oh, that's something the MRI tech uses, and he's a lowly TECH. None of that for us!
