In May 2018 SIX had announced a strategic partnership with Worldline in the cards business (merchant acceptance & acquiring and international card processing). From a strategic point of view SIX Payment Services and Worldline complement each other very well in terms of geographic reach and product offering.

The combined enterprise is now the leading and largest European provider in the payments services industry.
