For security reasons, blue Cumulus vouchers can only be redeemed at Subito checkouts if the digital Cumulus code from the Migros app is scanned (not the code on the card or stickers).
Digital Cumulus vouchers must be activated on the Migros app before or during the payment process. This amount is then deducted from the purchase price automatically.
At a Subito self-checkout, the Cumulus code is scanned as soon as it is displayed on the screen.
When self-scanning with Subito, the Cumulus code is scanned at two locations: at the scanner issuing station and the payment station. The physical Cumulus card or sticker can be scanned at the issuing station, but the digital Cumulus code on the Migros app must be scanned at the payment station.
