I'm a little worried about the security issues invovled when I think about one of these being stolen.

Could someone check into a hospital, essentially steal my identity because they've stolen my tag (assuming they copied the info and returned the unit and the theft went unnoticed), and then I get a bill in the mail?

I get nutty about the information I keep on my home 'puter, and that's got firewalls, several doors and an alarm system between it and the outside world.

I cross shred all of my mail, even if it's only adressed to "Resident". <img src="/images/graemlins/laugh.gif" alt="" />

Is it a case of paranoia due to the amount of "Identity Theft" commercials, reports and so on that I see? I don't know.

Value wise... Wow, it could be an extremely powerful and helpful tool in emergency situations. I'm torn.
