Identity cards can be used to locate individuals who are in danger  As biometric identity cards would be able to store medical data, they could be instrumental in saving somebody’s life. For example, if somebody suddenly suffered an epileptic fit, it would be much faster for medical staff to find out their illness and medical history no matter where there medical records are held as everyone’s records would be linked to their ID card [1] , allowing them to be treated faster and more efficiently. It would also be easier to contact a friend or relative if they knew the last place where they had used their identity card, allowing faster unity of family in a medical emergency.
