Making commuters’ lives easier with highly secure and open standard products

CityGO Calypso ticketing product range

Trusted by 160 transport networks and cities around the world, Calypso™ is the most used transport ticketing open standard in the world. This fosters innovation focusing on interoperability, top-notch security and end-user convenience. As a strong advocate of open standard benefits and long-standing member of the Calypso Network Association (CNA), IDEMIA actively participates in developing the Calypso™ standard.

IDEMIA’s cityGO Calypso™ products are all CNA-certified. These multi-application cards can be used as public transport cards and student cards (access management, canteen, library, etc.) or “citizen daily life” cards to use public services (library, swimming-pool, recycling center, etc.).

The cityGO Calypso™ range includes the IDEMIA COSMO Fly v6, the first CNA-certified Java Open card to encompass both payment and transport capabilities.


CityGO Calypso™ products are built around a certified common criteria ensuring watertight chip security.

Open standard

CityGO Calypso™ products come with extensive ticketing services beyond merely using public transport.


CityGO Calypso™ cards are fully compatible with existing Calypso™ automated fare collection systems: vending machines, gates, validators, etc.

Our certification policy ensures both compliance to the specifications and that the security and interoperability of Calypso™ products are respected. We are very pleased to add the first payment-transportation card using the CNA Java applet to our range of certified products, and we thank IDEMIA for enriching and diversifying the Calypso™ offer.
