Did you know that you can add emergency contact and health information about yourself directly on your iPhone lock screen? This could prove to be valuable information to friends, coworkers, or emergency services if you find yourself having a medical emergency and possibly unresponsive.

You can set this up if you have iOS 8 or higher system installed on your iPhone. Open up the pre-installed health app and select the Medical ID icon at the bottom. You can add information such as allergies, medications, blood type, and if you are an organ donor.

Since the information is available on the lock-screen, there is no need for people to know your password, and they will not be able to access the other information stored on your phone.
