About the Company

We are a payments solutions company providing financial institutions with technology, payments subject matter expertise and multi-disciplined services.

The Icon Payments Framework (IPF) is the framework that underpins payments orchestration solutions, and sits at the heart of the core payments architecture of banks such as Citi, UBS, NatWest and BNP Paribas. Leveraging the IPF software development kit, banks can easily, quickly and safely deliver payments systems with a low total cost of ownership. IPF also features a range of additional optional modules and ready-made integration to clearing and settlement schemes to accelerate the implementation of end-to-end payments solutions.
