Efficient Card Solutions and Reliable Services for Banks

SIX provides banks with flexible solutions for processing and managing debit cards, tailored to meet their individual requirements. We cover the full spectrum of international debit card brands as well as proprietary bank cards. 

Our offering is continuously enhanced with innovative additional services — from real-time fraud prevention and detection to dispute management, the debiX+ app, APIs, and TWINT services, all supported by a 24/7 customer service including a blocking hotline. If you're looking to outsource processes related to your debit card program, we bring extensive experience and cutting-edge technology to the table.

Customer Service Center and Direct Bank Support

In our Customer Service Center (CSC), our card experts are happy to assist your customers in four languages.

In addition, SIX supports debit issuers with all questions related to card processing, the analysis of fraud cases, and the handling of disputes and claims.

The Customer Service Center also provides full TWINT support on behalf of the issuer.

Card Fraud – No Chance

In our explanatory film (in German), we use the example of phishing to demonstrate how fraudsters operate and how customers of financial service providers can protect themselves against card fraud. Our goal is to ensure that Switzerland's most popular means of payment remains secure.
