Trionis is the new name for the interbank processing network formerly managed by EUFISERV. Trionis is a Brussels-based company jointly owned by retail banks from four European countries, and the European Savings Banks Group. Its mission is to develop, maintain and operate international payment services for the financial industry.

Our unique ownership structure combines the experience and focus of a leading commercial payments processor with substantial European bank equity and Board participation.

Increased choice from a truly European business

Trionis is based in Brussels, with a European management team who understand the market dynamics and complexities within Europe and who are able to deliver the quality, reliability and cost effective services required by our clients across the cards payments industry.

In full support of the vision of a single European payments market, the Trionis interbank processing Network expands the choice now available to financial and payment organisations wishing to process transactions within the SEPA zone or outside of SEPA.

Whether you are looking to manage scheme compliance costs in your local market; link to other banks for switching of interbank cross border and domestic transactions; consolidate multi-country operations to a single point; or, grow your existing business in the new SEPA environment through linking to other domestic schemes, Trionis has the infrastructure, knowledge and experience to deliver the services which meet your requirements.

The Trionis Network will provide extensive European coverage for its clients. Trionis provides processing services to its users for switching POS and ATM card payment transactions on EUFISERV and all other payment card brands, including American Express, UnionPay, Diners Club/Discover, MasterCard, and Visa.
