Using your My Number card as a health insurance card

Note: Using your My Number card can only be done at medical institutions and pharmacies that have a card reader installed.
Note: You can still receive medical treatment with your health insurance card as usual.
Note: Initial registration is required to use your health insurance card.

The quality of medical care can be improved by being able to diagnose and prescribe according to your own information.
There will be no need to make lump-sum payments above the limit at medical institutions or pharmacies.
