Jeff hit it on the head. I would never stick a USB into the computer on my ambulance (back when I was in the field), even if the computer DID have a USB. Which I don't think it did.

And nowadays, I sure wouldn't stick it onto my hospital computer! No way. I don't care what fancy packaging it came in.

Dog tag, ID bracelet, or wallet card. That's it. If I can't Xerox it and throw it onto your chart, it's no good.

For all the gee-whiz crowd out there, if you want something electronic, there are some things that you can keep your info online, and the bracelet directs the provider to either a website or phone number. That might be a better option, though it still depends on someone sitting down and killing time waiting for the info.
