My cellphone (Apple) has an ICE (no, not that one) facility "In Case of Emergency" with NOK information and contact number*, but I like the look of that bracelet Hawk. I will research.
* So even on screen lock you can see an Emergency option bottom left of the screen. Touching that opens an emergency call screen (for 911 / 999 / 112 calls) then bottom left of that screen is a medical ID option which lists NOK, contact numbers, medical conditions & Blood type.
