How can I store my Cumulus code outside the Migros app? – Migros Help

You have two options:

As a widget: Press and hold your home screen, tap “Edit” and then “Add widget” (iOS) or “Widgets” (Android). Search for “Migros” and add the Cumulus widget. This way your Cumulus QR code is always directly accessible without opening the app.
In Apple or Google Wallet: In the Migros app, go to the “Home” tab. Make sure you are in the shopping mode “Shop in store” (top left). Tap on “Cumulus code” and add it from there to your Apple or Google Wallet.
