It can include a physical card, bracelet, keychain, or app that stores medical conditions, allergies, health insurance provider, emergency contacts, physician contact information and more. It is useful in medical emergencies when timely access to critical medical information is needed. In addition, MEDID can be used to provide vital medical information to treating physicians in cases of medical emergencies.
