◆Operation at reception
The reception procedure at medical institutions, etc., uses a card reader with face recognition, in the same way as when accepting a medical application with a mina-number insurance card. Select the appropriate terminal on the reception screen, authenticate yourself at the terminal, and proceed to enter consent information when you hold your smartphone-equipped mina-insurance card over the general-purpose card reader for smartphones.
◆How long can I use the conventional health insurance card?
Conventional health insurance cards will expire sequentially (the longest expiration date is December 1 of this year) as a result of the transition to the myna insurance card. Therefore, for those who do not have a Myna insurance card or have not registered to use the Myna insurance card, a “certificate of eligibility” will be issued by the health insurance association or local government (for those who are enrolled in the late-stage medical care system for the elderly or those who are newly enrolled in the system, a certificate of eligibility will be issued as a provisional measure until the end of July 2026 regardless of whether they have a Myna insurance card or not. (This is a provisional measure until the end of July 2026 for those enrolled in the Late-Stage Senior Citizen’s Health Care System and new enrollees, etc., regardless of their Myna insurance card status.) If you present this card at the counter of a medical institution, you will be able to receive insured medical treatment as before.
