Mark M, if you already have your emergency medical information on your person, I am just curious why you would also carry the USB with your medical information on it? Why risk it (from a confidentiality POV). Also if the emergency medical info is on your person, the need to be conscious would be less critical as the excess medical info would not necessarily need to be accessed right away, thus the USB info could be encrypted IMO. Am I missing anything else? Always learning, always taking notes .
