I am not sure if everyone knows this, but recently reread an article about this. Should be useful to most people. I directly copied and paste partially of what was found in wiki.
In Case of Emergency, or ICE, is a program that enables first responders, such as paramedics, firefighters, police officers, to identify victims and contact their next of kin to obtain important medical information. The program was conceived in the mid-2000s and promoted by British paramedic Bob Brotchie in May 2005. It encourages people to enter emergency contacts in their cell phone address book under the name ICE; alternatively, if a person has multiple emergency contacts, they can be listed similarly to the following: ICE1-Mom, ICE2-Dad, ICE3, etc. The popularity of the program has spread across Europe, and has started to grow into North America.
