The Medical Passport consists of an NFC tag and an Android application. The app works with structured and normalized data and allows the user to write the tag with relevant medical information such as allergies, diseases, blood type, health insurance, medication, as well as other important information such as an emergency contact, birth year, nationality,etc. The tag can be read using the app or with another NFC app. The information recorded in the tag can be reliably translated to the reader's language due to information normalization. The reader of the tag will usually be a health professional, who will make use of the information recorded by the patient in order to provide a better medical care. Moreover, the prototype here presented will have an offline mode.
