You can set or change the "main image" (the certificate image shown first) on the Home screen.
Setting a page with a face photo as the main image is convenient when you show the app.
* You can set this only if more than one certificate image is registered.
How to set or change it
1. On the Home screen, swipe the certificate image, or tap the "＜" or "＞" button, to show the certificate image you want displayed first.
2. Tap the certificate image you want displayed first to enlarge it.
3. Tap the "Set as Main" button at the bottom.
4. When "This image has been set as the main photo." appears, the setting is complete.
On the Home screen, confirm that the main image (the certificate image shown first) has been changed.
