At the moment, the Coverflex card does not yet support integration with digital wallets, but - great news - you can now add the Coverflex card to Apple and Google Pay. Just go to your profile, and depending on which phone you are using, you will have the option to add the card.
Regarding MB Way, there is currently no integration with the Coverflex card. If one day this feature is released, you will be the first one to know!
