If the person you're assisting wants the MitID app on their own phone/tablet, first you have to download the MitID app from the Apple App Store or Google Play on the phone/tablet, where you want to install the MitID app.
Next, make sure that Bluetooth is enabled on both devices. You can enable Bluetooth in the settings of your phone or tablet.
The MitID app on the phone you used to scan the passport is still active. If you no longer want to use it, you can delete it.
If the person you are helping wants, for example, a MitID code display, choose this option.
