Since STET's funding, our vision is that the payments market will retain national differences for a number of years. The reality of the European clearing market shows that it is multi-currency, multi-payment instruments - SEPA and non-SEPA including Cards - and consumer preference for these varies by community. That's why we always dedicate to serve the diverse needs of the market.

2004-2015: STET develops and operates the CORE system

In 2004, with the emergence of the SEPA, STET was created by a group of major French banks with a particular goal in mind: to undertake the development of a new platform that would meet the transformation and challenges the payments industry was set to undergo.

Built on years of experience and expertise, the CORE platform was developed with the ambition to create an innovative payment platform for the future European market. This new platform aimed to deliver efficiency and security to a large-volume market, and to provide the requisite architectural flexibility to handle the diversity that would exist for many years.

CORE was successfully launched in January 2008 with the first SEPA SCT payment and, throughout the year, hosted the migration of the full range of payment instruments in the French market. This was in addition a national consolidation of the clearing by concentrating all payment instruments in a single clearing system.

In 2012, our technical consolidation approach became a reality when the Belgian banking community entrusted STET with the processing, clearing and settlement of SEPA and non-SEPA payment instruments in the Belgian market.

The implementation of the new Belgian CSM ended in March 2013.

2016: STET deepens its expertise in Cards by merging with SER2S

On 18, December, 2015, Stet merged with SER2S, becoming STET SA.

Since January 2016, STET operates the secure E-rsb transport network for cash withdrawal and payment authorisation messages.

With the addition of this network, STET activities now include a strong expertise in cards, as well as the study, design, building and operation of networks and secure interchange and data processing systems, in the context of electronic payment systems.

This operation reinforces STET's strategy to deliver the payment market with state-of-the -art solutions in terms of Real time processing, security, and 24/7 availability.
