If you have a medical issue such as a seizure disorder, cardiac condition, or similar problem that may leave you unable to communicate with medics and other first responders, it's important to have a simple method they can use to understand your situation so they can best help you. While a medical alert bracelet, id bracelet, or even a medical id card in your wallet may help in an emergency, there's one more tool you can use to ensure you receive the prompt care you need—your iPhone! Even if you keep your iPhone locked with a passcode or Touch or Face ID, it's still possible to have your Medical ID visible on your smartphone so that bystanders and emergency personnel can assist you in a medical emergency. Let's get started learning how to add an emergency medical card to the Lock screen on your iPhone.
