@kjoed53 In addition to the RoadID mentioned below, there is MyID and a few others that are easily recognized, don't require a paid subscription, and can be updated on-line without being replaced. These carry a code for looking up your information, accessible to ER's and EMS (Emergency Medical Services.) You can also include and update a list of all of your medications and allergies, as well as people to contact (can be more than one.)
