Recently, the concept of "ICE" is catching up quickly. It is simply, an important method of contact during emergency situations.
As cell phones are carried by majority of the population, all you need to do is store the number of a contact person or person who should be contacted at during emergency as "ICE" (meaning In Case of Emergency).
The idea was thought up by a paramedic who found that when they went to the scenes of accidents, there were always mobile phones with patients, but they didn't know which number to call.
