About Calypso Networks Association (CNA)

Calypso Networks Association (CNA) is a not-for-profit organisation which brings members of the transport, mobility and services community together to exchange ideas, experiences and requirements to advance open systems that support seamless, consumer ticketing needs.

The CNA community combines transport and mobility authorities, operators, and service providers, as well as technology manufacturers and transport consultants. It is a diverse and welcoming community which spans public and private sector organisations.


As an open standards body, CNA empowers the community to control and evolve the smart ticketing ecosystem, so it advances smart ticketing systems and supports mobility as a service.

CNA regulates the use of Calypso technology, and delivers expert services, to promote open standards and enable their use across local, regional, national and global ticketing requirements. Its work is defined and driven by a global network of members.

New members are warmly invited to join the CNA community. All members of CNA receive exclusive membership benefits and ongoing support from the association. Through CNA’s working groups, its members shape the future direction of Calypso technology.

The important of open standards

Open standards give transport authorities and operators control of their ticketing network. It provides the reassurance that they have a sustainable framework that can evolve and support new technical trends and business requirements in a cost-effective way. Over 50 manufacturers supply Calypso products, solutions and services, providing multi-sourcing options and enabling competitive bidding over time. There is no vendor lock-in.

The transport authorities and operators are invited to influence the strategic and technical direction of Calypso technology by joining and contributing to CNA.

CNA’s missions

CNA’s mission is to support the use of the open Calypso technology standard to enable transport and mobility operators to control and advance their contactless ticketing systems. This is achieved by:

  • Promoting competition and lowering lifecycle management costs by encouraging open standards and avoiding vendor ‘lock-in’
  • Sharing knowledge, experiences and expertise through education and networking
  • Supporting innovation by removing fragmentation and creating a technically secure ‘baseline’ on which stakeholders can build upon
  • Encouraging the use of open source software, which is accessible and usable by all
  • Advancing global standardisation through the development of interoperable systems and standards
