ICE is a suffix you add to contacts in your phone that you want notified if you end up in, say, hospital having been found unconscious - i.e. you're already in the hands of the emergency services, not summoning them. How some A&E nurse is supposed to nosey through your contacts when she doesn't know the pattern for your unlock screen is a mystery, however.
Which will be ignored. I have a Medic-Alert bracelet for a penicillin allergy, during the 8 weeks I was in an EMT course only one student noticed it, despite all of them using that wrist to check my pulse. Also after to vehicle accidents, the medics also failed to notice it, again after checking the pulse on that wrist. On on accident, I was on duty and had my blood type and allergy written in huge white block letters on my body armor.I think I'd rather they just flicked open my wallet and saw the critical info (allergies/meds, etc.) and NoK details card in the bit with the window in it, really.
It must have been quite a chore when the automatic exchanges were introduced in London to match the alpha-numeric codes on the old pulse telephones to meaningful and memorable words (like WHI- Whitehall )Whats wrong with Whitehall 1212 or 2301212.
Face ID or Touch ID should work unless you've been mangled a bit.
Nowadays I would not rely on the emergency services to find me! I will take my chance with first responders.For when you absolutely, positively need the emergency services to be faffing about with your phone instead of saving your life.
