Solutions Overview

CNA is the governing body of Calypso technology

Calypso® is an open, secure ticketing standard that promotes innovation and is used in more than 25 countries and over 170 cities globally. It has been designed by transport operators for transport operators to ensure long-term usability.

As the needs, expectations and behaviours of travellers are so diverse, it is impossible to meet them all with a single ticketing solution. To reflect this, the Calypso standard supports a wide product portfolio to accommodate all traveller needs, regular or occasional, in any configuration, media or system.


Calypso for Cards

The Calypso standard supports three main product lines: Calypso Prime, Calypso Light and Calypso Basic. All products are part of the same family, with the same security mechanisms and the same unique software in the reader, to achieve the required level of protection, ensure compatibility and ease the integration.
