In short +++ungood. Pre-hospital care notifications are best handled by human-readable systems (read: Medic-Alert tags, Tatoos). I have NEVER seen a laptop pulled out by a medic on a call, and to be blunt, when your arms are off, we don't care if you're allergic to peanuts - WE'RE NOT SERVING MEALS OUT THERE!!!!

Now, let's cut on the technology in general:

1.From the site:
"Zaptag is a small rugged and water resistant USB drive powered by Sandisk USA. Zaptag incorporates Windows-compatible software that enables you to create personal records that can be accessed in times of emergency." Wait a minute - this is a Sandisk Cruzer Micro wrapped in plastic. My Cruzer micro has been through the wash as often as my socks. And the cruiser micro is like $10 for a small capacity one.

2. "The drive itself is extremely rugged and can be submerged in water up to 4ft, making it the ultimate travellers companion."
FOUR feet? Umm....no thanks. I want something that will survive at least the freaking water park, not to mention ditching over water!

3. WHAT medical records? Sorry, but I've seen my medical records for the last 10 years - it's a file folder. In a few places I've had medical records created that were electronic -most recently when I broke my wrist the X-Ray was a digital file - BUT when it came time to see the osteopath, they were not able to send him the digial image file - I got a print.

Look, I'm just as geeky as the next person, but the fact is that some things just might be impossible to digitize because of the necessary decades long double work of making human and machine readable records available at the same time.
