    Open Banking

    Acting as a Payment Initiation Service Provider, Nuapay allows you to offer your users the option to pay via their bank account. For your users that means that they don't need to use a credit card and because they are verifying their credentials on their own online banking portal, they can be confident that their personal data is secure.

    For you, the merchant, no chargebacks are possible and funds are credited to your account in real time (via Faster Payments). Cheaper than card payments, we really believe that Open Banking is a game changer for any business handling online payments

    As per Article 38 of the supplementing Directive (EU) 2015/2366 of the European Parliament and of the Council with regard to regulatory technical standards for strong customer authentication and common and secure open standards of communication, Nuapay as a Payment Institute has published its Open API/Swagger specification to enable TPPs to access Nuapay AIS and PIS services.
