Apple and other tech companies have realised that the ability to show medical or emergency information on the ‘lock’ screen of a phone or smart watch is vital, and could make a difference to the outcome of an emergency.  Increasingly, paramedics and other rescue professionals are going straight to a casualties phone to find this information, in the hope that it has been input. 

Apple iOS

1. Open the Health App and tap Medical ID > Edit.
2. Enter your preferred emergency contacts and health information like your birth date, height, and blood type.
3. Make sure you turn on Show When Locked to make your Medical ID available from the Lock screen. In an emergency, this gives people who want to help some important information, like the emergency contacts that you’ve entered.
4. When you’re finished, tap Done.

Android (Pre Jellybean)

Android Phones that pre-date the Jellybean update have In Case of Emergency (ICE) contacts as a default feature. To set this, go to your contacts and follow the below steps:

1. Select the “Groups” tab.
2. Select “ICE – Emergency Contacts”.
3. Use the icon to the right of “Find contacts” (a plus sign) to add an emergency contact.
4. Select or add a new contact to the group.
5. All contacts in this group will be available from the lock screen, so you can call them without unlocking your phone

NOTE: Alternatively you can make the first name of your contact “ICE” and the last name the entire name of your contact. However, if the contact is not in the ICE group their information in not accessible if the phone is locked.
