The 'high tech' documentation is a good idea but often in emergency situations there isn't a quick/easy way to access it. To be really helpful it has to be RIGHT NOW. That's why an ID bracelet, necklace, watch fob or whatever is still the best way to go. Put the key info on a printed card in your wallet and that's what will work. EMS can spot the ID and know of an issue and the wallet card or even an info card on a necklace will be the emergency data needed for the first few minutes and/or that initial hour.

Go ahead and keep a full history and all sorts of supporting info on an SD card, USB drive or whatever too for every day carry but, the key info (diabetic, heart condition or whatever) is time critical and that's minutes - not until somebody can find a computer to look up your info. Just saying...
