Instant Payment App Development for Mobile Banking

The Client and the Challenge

Belitsoft was contacted by the founders of a startup from one of the EU Member States. They wanted to create a mobile app that would support SEPA Instant Credit Transfer (SCT Inst) scheme to make real-time payments. PayPal became an investor of this startup.

SEPA scheme cover 36 countries and territories, including 28 EU Member States, as well as Iceland, Norway, Liechtenstein, Switzerland, Monaco, San Marino, Andorra, and Vatican City State/Holy See.

Today 2079 payment service providers (PSPs) have already joined the scheme (51% of European PSPs).

According to the PSD2’s Regulatory Technical Standards (RTS), banks across the EU are required to have implemented their dedicated interfaces (open API) for third parties to use by September 2019. But the majority of banks across the EU are still struggling to implement the technical requirements of the directive - the APIs available up to now are far from ready, lacking the quality and maturity they need (UK banks are more advanced in their progress).
