As a member-driven community, CNA facilitates collaboration through strategic working groups. By joining these workshops, members have an important opportunity to communicate their needs to the smart ticketing community, and refine the technology to suit the practical requirements of organisations worldwide.
CNA’s strategic priorities are organised within four working groups
WG1 – Improving and developing Calypso’s 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 standardisation initiatives to encourage industry best practice.
WG4 – Supporting the promotion of Calypso and its benefits through dedicated events, communications and marketing.
The CNA team provides ongoing dedicated resource and expertise to progress the key activities within each working group.
WG1 is open to all CNA members and has a number of dedicated sub-groups. Each sub-group is dedicated to a specific priority and is an opportunity for members to collaborate on requirements, agree best practice and secure agreement, prior to submitting it to the CNA board for approval.
WG1 is structured to facilitate flexible participation, so members can contribute based on their relevant experience, whether that is by reviewing a draft technical document or actively contributing to each regular meeting. All meetings can be joined virtually, promoting ease of access.
Active Groups in WG1 include:
- Account based ticketing (ABT)
Exploring how to introduce ABT in a range of solutions including cards, mobile ticketing and open payments, and identifying Calypso’s role in ABT. - Calypso’s range of products

WG2 is comprised of members of CNA who have signed the Hoplink charter, and led by the Chairperson of the Hoplink college. WG2 is open to all Adhering and Effective members who intend to join the Hoplink community, either by implementing Hoplink within their network, or as a provider of related solutions.
WG3 and WG4 are managed by CNA’s expert team to drive forward promotional activities for the organisation. All CNA members are welcome to support CNA’s promotional activities for the greater good of the association.
