The insertable ID tag would be good if it could be updated without having to remove it. If mine were updated every time I have an asthma attack, medication or a new injury/illness, I'd be forever in and out with the thing and would be better off having a zipper installed!

Having a link to a computer (as most hospitals have now) would be more sensible. Zap in the barcode and the info appears on screen, a bit like your details appear when you give your post code (zip code) to any retail outlet offering credit facilities or any phone purchasing outlet. Tap in the post code, they have you to within 100 houses. Standing behind a bloke wanting to buy something on his credit card in the Electronics shop this afternoon, the bloke was asked for every thing except his inside leg measurement and the birth weight of his first born child.... all of the required info was already on screen, they just needed confirmation.... right down to his previous 4 addresses and his mother's maiden name! Orwell wasn't so far wrong....
