How to lead ticketing to Open Source

Coming from a rather closed technical and industrial environment, public transport relies more and more on open solutions. This movement towards openness is very clear in the field of passenger information, open data is now the rule, and, on a global scale, the main transport operators have taken this way. Through APIs, open source software and thanks to a free access to data, many developers offer applications for the benefice of the customer, with an easier access to multimodal transport, including sustainable modes.

But at this stage ticketing still remains in a quite closed environment with manufacturers providing proprietary solutions. For many years, Calypso has been a de facto ticketing standard, open in the meaning that it is accessible to all manufacturers without any restrictions. Today Calypso strongly thinks that ticketing has to follow the same way than passenger information and go to open source solutions. And so Calypso offers free of charge, in an open source business model, tools such as an applet for mobile phones and such as Triangle the interoperable ticketing application. And a SDK, Keyple, a very powerful API for integrating different kind of systems, traditional ones or Account Based Ticketing ones will be available in a few months.

Thanks to these tools, open source will also enter, for the first time, the world of ticketing solutions.

On another point of view, ticketing cannot strictly follow the example of passenger information, since it is dedicated to manage the revenues of public transport. Issues such as guarantee of security, guarantee of interoperability, etc. requires a strong governance: here is the role of CNA, the Association of users and providers of Calypso, to offer simultaneously these guarantees and open source solutions.
