The Premium Passport app is an official application designed to assist families with children under 18 in Ishikawa Prefecture. It offers various features, including the ability to display a digital passport, access event information, and utilize a family invitation function. The app's offline capability allows users to view their passport even without internet access, enhancing convenience for families on the go.

This application is part of an initiative to support parenting through community engagement and offers discounts at participating businesses when the passport is presented. Users can manage their account information, view registered family members, and invite others to join the program, although the invitation and account updates require identity verification and an internet connection.
