Cardholders, particularly younger people who pay for retail purchases predominantly by using mobile phones, are the target consumer segment for Mastercard One Credential, a service from card issuers that lets buyers preset or switch their payment product preferences. Issuers will offer Mastercard One Credential online and through their mobile banking app. Mastercard will provide them with reference design templates that can be customized to create a One Credential user interface that lets cardholders select payment preferences.
