Open Banking Compliance Architecture

What is Open Banking Compliance Architecture?

In the age of digital finance, compliance is not just a requirement but a cornerstone for trust and integrity. obconnect specialises in Open Banking architecture designed for banks and financial institutions that need to meet PSD2 Regulatory Compliance.

With PSD2, organisations must provide real-time access to APIs for FCA Regulated Third Party Suppliers (TPPs) and Fintechs. These APIs facilitate Account Information Requests and Payment Initiation. 

Open Banking is the UK’s standard approach for PSD2 compliance, and with obconnect, achieving this is streamlined and secure.
