This page describes the Public Medical Hub (PMH), a system developed by the Digital Agency to connect municipalities, medical institutions, and pharmacies through information exchange utilizing My Number Cards. In the medical subsidy field, users can employ their My Number Card as a benefit certificate. In vaccination and maternal health services, users can complete questionnaires via smartphones and track vaccination histories and health check results in real-time through the My Number Portal. A pilot program began in fiscal year 2023, with ongoing expansion of participating municipalities and medical institutions.
