And by the way ... back to the medical info.

While I am intrigued by the possibility of carrying a USB key - I would not rely on that method at all. If you know that you have specific medical issues, get them stamped onto some sort of dog tag and wear it around your neck. The tag does not have to be big - get the writing done in a concise way, but still readable in English. It is always advisable to keep things as simple as possible for an emergency situation.

For example ...

"John Doe. Blood type O+. Allergic to penicillin. Suffers epileptic seizures."

Keep it that simple. It gets across the absolute basics - not your whole life story. Wear the dog tag around your neck - because any EMT who's got a shred of sense will check your neck first for a carotid pulse. Hopefully they will notice the tag at that time (or the hospital will later). You can always be selective about when your decide to wear the tag, and when you don't.
