Towards a pan-European payment system 

A huge standardisation movement accompanied by appropriate legislation was launched at the European level as part of the SEPA (Single Euro Payments Area).


CB is playing a driving role in this context alongside other key players in card payment systems in various European countries, including: Germany, Belgium, Denmark, Spain, Holland, Italy, the United Kingdom, Norway, the Netherlands, Portugal and Sweden.


This European standards and legislative process covers all elements of the card payment value chain, namely:


  • The payment terminals 
  • The exchange protocols
  • The harmonisation of security requirements
  • The bank cards
  • The certification of products/solutions stated below

All of this work goes beyond the framework of SEPA and now covers all requirements of the international e-cash community.



NEXONEXO is an international non-profit-making association resulting from the merger of EPASOrg, the OSCar consortium and the working group EMV Common Implementation Recommendations (CIR). It includes 64 members including all players in the e-cash value chain (merchants, card payment systems, payment solutions providers, payment transactions processes, bank acquirers and international associations).


Its objectives are:


  • to produce standards which meet the requirements of the card payments market;
  • to harmonise European standards to guarantee interoperability and strengthen the security of exchanges;
  • to provide fluidity in transactions and cost optimisation to merchants operating mainly internationally.

To perform these tasks, Nexo uses innovative specifications and protocols: the EPAS protocols (international ISO 20022 standards) the SEPA-FAST and OSCar specifications (OIS specifications).




The European Card Payment Association covers the domestic card systems of each European country and the organisations responsible for fundamental functions such as the certification of hardware used in the card payments value chain.


The ECPA is a vector of cooperation and the representative voice of its members to European institutions such as the European Commission, the European Central Bank, the European Banking Authority and other stakeholders on subjects such as legislation, security and standardisation in the field of card payments.





OSeC (Open Standards for Security and Certification) is a European payment systems initiative extending the European work of the CAS (Common Approval Scheme) group in the field of payment terminals (POI – Point of Interaction).


The objective of OSeC is to coordinate pilots intended to validate the feasibility of security developments to the POI according to the Common Criteria (CC) methodology.


The certificates obtained may then be recognised by the various payment systems in their respective certification processes, thus simplifying and reducing the cost of the certification process in the SEPA.
