A medical identification tag is a small emblem or tag worn on a bracelet, neck chain, or on the clothing bearing a message that the wearer has an important medical condition that might require immediate attention. The tag is often made out of stainless steel or sterling silver. The intention is to alert a paramedic, physician, emergency department personnel or other first responders (emergency medical services, community first responder, Emergency medical responder) of the condition even if the wearer is not conscious enough, old enough, or too injured to explain. A wallet card with the same information may be used instead of or along with a tag, and a stick-on medical ID tag may be added or used alone.
