PSD2 Compliance is a customer-centered regulation that is intended to improve the general user experience, which should benefit both the customers and the banks/payment service providers. Drafted and administrated by EU, PSD2 enforces a set of regulatory rules that requires banking institutions to make interfaces available to third-party payment institutions.

As a result of the Act, WorldFirst is also subject to the regulations, and provides a set of PSD2 APIs. These interfaces include functions such as account inquiry and making transfer requests.
