The 'ICE' acronym was developed as a way to put a next to kin in a cell phone. 'ICE' stands for "In case of emergency."
In the case of an emergency, emergency responders on scene can open your cell phone and scroll down to your ICE contact to call a family member and inform them of an emergency. This can be vital in an emergency because if you're unresponsive, medical responders can ask the 'ICE' contact important medical information. Responders can also inform the 'ICE' person of the incident.
