The "Kids' My Number Card Is Too Hard" Problem: Won't Face Recognition Work as They Grow?

My Number cards may not issue signature electronic certificates to those under 15.

Using the JPKI PIN reset app on a child's card requires face authentication.

Face authentication can fail as children grow, causing lockouts; cases reported include differences between age 14 and university and newborns failing after months.

From the end of 2025, health insurance cards will largely be abolished, and My Number cards will be required at medical institutions for adults and children.

Hospitals use My Number cards at reception, but high terminal placement can make face authentication difficult for infants and elementary-age children; local medical certificates may also be required.
