Designing an emergency medical card that shares only essentials when a patient cannot consent

A team building the Anpheros emergency card describes how it should work when a stranger scans a QR code on an unconscious person's phone. The page shows only actionable basics such as identity, age, blood group, allergies, vaccinations, current medications and emergency contacts, with no access to full medical history. Full records require a clinician's request that the patient approves later, by scope and duration. Medications were debated, with options including filtering high-risk drug classes automatically or showing only what the person selects. To work across languages, the card stores coded data such as SNOMED CT, ICD-10, ATC and LOINC codes, aligned with the International Patient Summary and SMART Health Links standards.
