CNA association


CNA, Calypso Networks Association, is a non-for-profit association under the Belgium law of an ASBL, dedicated to develop and promote Calypso.

At the end of the Calypso European Project, and given its great success, it appears clear to its participants that it was necessary to extend their cooperation in order to guarantee the evolution of the specifications and the promotion of Calypso on a global scale. The originality, and the strength, of Calypso, its independence from a manufacturer, clearly needs to be conserved.

Consequently they decided to sustain the existing club of users and to reinforce its role and its missions by creating the Calypso Network Association (CNA). This initiative received the full support of the European Commission, as a way to ensure the diffusion of the results of Calypso as widely as possible.

CNA was established in Brussels as a non-for-profit association under the Belgium law (ASBL) in 2003, with the founder members of the project (OTLIS-Lisbon, ACTV-Venice, STIB-Brussels, LKRKN-Constance and RATP & SNCF-Paris).

The objectives of CNA are to:

  • Establish long lasting relations between all the partners using Calypso specifications.
  • Define and direct the reference specifications.
  • Implement a certification policy, to guarantee the compatibility of all current and future products.
  • Establish a Calypso label issued by an independent organization.
  • Promote Calypso to operators and manufacturers to yield its distribution.
  • Contribute to the international standardization process.
  • Facilitate and harmonize the shared members' needs and experiences.
  • Encourage all actions of mutual assistance in the implementation of Calypso e- ticketing systems.
  • Promote and manage the Hoplink solution for interoperability.
  • Encourage the initiatives to associate Calypso ticketing applications in multiservice environments.

The CNA statutes describe the management and the governance of CNA.

Working group description




Working Group Organisation

CNA activities take shape through the creation of task forces; the main working groups are:

• WG1:  improving and developing Calypso reference specification, to provide an appropriate solution to transport operator needs.

• WG2:  favouring interoperability between transport networks, and amongst networks, to ensure that any Calypso Portable Object can work with any Calypso terminal.

• WG3:  promoting Calypso technology worldwide and participating in national and international standardization initiatives so that Calypso’s good practices will spread throughout the community.

The technical working group WG1 welcomes all contributors who are willing to participate and bring their own expertise: operators, industry vendors and manufacturers, consultants, software houses, and so on.

Its main objective is to ensure a constant improvement of the security features of Calypso. The second objective is to set up and maintain a policy of certification for the different products used in Calypso systems. Another focus is to facilitate the emergence of new technologies and services in the Calypso environment by providing solutions to the world of transport.

The WG1 is organized around Working Packages according to the related topics. Each Package is managed by a company leader, chosen by CNA and paid accordingly.

An internet collaborative tool federates the Working Packages: .

Every CNA member can participate at different levels: from a simple following of the discussions on the dedicated forums, through a review of the draft documents of specification, and until a more active participation in the regular meetings (also available via web conference).


Main achievements

The goal of each working package, is to find a general agreement on a specification document before to submit it to the board of CNA for approval.

These documents are available for the CNA members.


Following main and recent achievements can be highlighted:

• The specification of a Calypso Light Application (CLAP), and its associated functional test plan.

• The specification of a Calypso HCE Application.

• The User Manual of the version 1.3 of the Calypso CNA applet, which aims at promoting Calypso on NFC phones.

• The last revision 3.2 of the Calypso Portable Object Specification, with AES crypto algorithm and new features for privacy data protection.

CNA Partners


CNA established numerous and fruitful partnerships and cooperation with other associations and organisms who share the same goals to facilitate seamless travels for customers, standardized solutions for operators and authorities, interoperability for both.

STA – The Smart Ticketing Alliance

The Smart Ticketing Alliance was established following an agreement by VDV ETS (DE), ITSO (UK), AFIMB (FR), Calypso Networks and UITP.

The Smart Ticketing Alliance is a platform for European and global cooperation. The founders of the Smart Ticketing Alliance invite other national and regional ticketing schemes to join.

Following the Memorandum of Understanding (MoU) signed February 2012, the Smart Ticketing Alliance has now been founded by representatives of the organizations of VDV ETS (Germany), ITSO (UK), AFIMB (France) and Calypso Networks Association, together with representatives of UITP (International Association of Public Transport).

This is another major step forward in making transport ticketing across parts of Europe simpler and easier for passengers: it creates a platform for cooperation throughout Europe and globally. The Alliance includes cooperation on, and establishment of, a trust scheme for Public Transport that mirrors the Trust Schemes in the mobile phone industry, banking etc.

The February 2012 agreement commits the Alliance to cooperate on the development of Smart Ticketing interoperability based on the principles of Interoperable Fare Management (IFM) set out in the EU-IFM Project funded by the European Commission and the developments in contactless bankcards and NFC-enabled devices, particularly mobile phones.

The Smart Ticketing Alliance represents a coordinated approach for establishing Smart Ticketing interoperability in the public transport sector.

The main goals of the Alliance are:

  • Cooperation between national and regional Smart Ticketing schemes to establish interoperable Smart Ticketing in Europe and elsewhere.
  • To develop, agree on and publish the functional and technical requirements for smart ticketing interoperability
  • Cooperation on the establishment of Trust Schemes, Specifications and Certification
  • Cooperation with other European and International bodies to promote interoperability in Smart Ticketing

Full membership is open for national ticketing schemes and regional groups of Public Transport Authorities/Companies cooperating in the electronic Smart Ticketing area. Associated members are welcome. The founding members of the Smart Ticketing Alliance invite other European stakeholders to join either as Full Members or at Associate level in the development of the Smart Ticketing Alliance. A coordinating Secretariat will be established for the Smart Ticketing Alliance from within the UITP to provide a single contact point.


ITSO Ltd. is the non-profit distributing organization that oversees the ITSO Specification for smart ticketing in the UK. ITSO helps its members to set up and run ITSO-compliant smart ticketing schemes, tests and certifies smart ticketing equipment to ensure it meets the ITSO standards and ensures the ITSO Specification is up to date and fit for purpose. ITSO operates the ITSO Security Management System (ISMS), a highly secure key management and distribution system specifically developed to enable ITSO-compliant smart ticketing systems to be set up.


VDV- ETS is the open and secure German standard for electronic fare management systems (EFM) which enables passenger to move freely and easily between public transport companies without having to deal with different tariff zones and ticket machines (interoperability). It provides an open platform which not only allows transport operators to integrate their back office systems as well as those of multimodal and multifunctional partners. The VDV-ETS regulates the cooperation of the various stakeholders in EFM systems at an organizational level (eTicket Germany is the brand name of the VDV ETS).


The French agency for multimodal information and smart-ticketing (AFIMB) is linked with the Ministry of Ecology, Sustainable Development and Energy. Its steering committee gathers representatives of transport authorities, users, transport operators and relevant public administrations. The agency aims to promote interoperability in the areas of multimodal information and smart-ticketing and supports standardization.


UITP is the international network for public transport authorities and operators, policy decision-makers, scientific institutes and the public transport supply and service industry. It is a platform for worldwide cooperation, business development and the sharing of know-how between its 3,400 members from 92 countries. UITP is the global advocate of public transport and sustainable mobility, and the promoter of innovations in the sector.


ADCET is a non-for-profit association created in 2005, and brings together public and private members to promote the development of electronic transactions in territories and universities in order to improve the lives of end-users and the communities’ management.

Its domains of intervention are: administrative procedures, purchasing, loyalty, parking and public transport, public services, tourism, universities, etc.

The main mission of ADCET is to contribute to the definition of standards in those domains in order to promote new, open and sustainable technical architectures, and a comprehensive range of services and products.

To achieve its objectives the ADCET conducts working groups among its members, informs stakeholders on market developments through its website, the social networks and a newsletter. It holds a yearly conference.
