Visa has introduced its Visa Intelligent Authorisation (VIA) solution in Europe, expanding the capabilities of the Visa Acceptance Platform for payment acquirers across the region.

The new service enables acquirers – including banks and other financial institutions that process payments for merchants – to modernise legacy payment systems via a single API connection.

Initial European partners include Comercia Global Payments, Elavon, Fiserv, UNICRE and Worldline.

Visa highlighted that legacy acquiring platforms are struggling with current payment volumes and data complexity, causing false declines, higher costs, and limiting innovation.

VIA is designed to tackle these issues by offering a modern authorisation capability able to process transactions across major card networks through a single integration.

Visa Europe head of Acceptance Sales Dan Parsons said: “When systems can’t keep up, the result is higher decline rates, increased costs and missed sales for merchants. Visa Intelligent Authorisation will help change that. It gives acquirers a fast path to modern, resilient processing, helping them build for what’s happening now, and what’s coming next.”

According to Visa, the solution delivers “99.999% uptime” and has an average “approval rate of 96.3% globally”.

VIA can operate as an acquirer’s primary processor or as an auxiliary service to extend existing functionality.

The platform uses a machine learning engine to analyse transaction data in real time and optimise routing decisions in line with network rules, industry programmes and regional regulations.

It also provides near real-time visibility of authorisation outcomes, instant risk alerts and a centralised portal with an analytics dashboard.

The European launch of VIA follows the expansion of Visa’s alliance with Fiserv, announced last week.

Under that agreement, the Visa Acceptance Platform is being embedded within Fiserv’s merchant acquiring and processing solutions across Europe. Visa’s API-driven acceptance layer will form part of Fiserv’s cloud-based acquiring infrastructure.

Commenting on the new capability, Fiserv SVP and head of Merchant Product EMEA Paul Adams said: “Visa Intelligent Authorisation gives acquirers a faster path to modern, resilient processing. For our merchants and bank partners, this kind of infrastructure matters – it reduces friction, improves approval performance, and creates space for innovation.”
