Keyple Ticketing

From Communauté de la Fabrique des Mobilités

Keyple Open source API for Ticketing

💼 porté par Calypso


The Calypso security guarantees a high level of security of the transaction between a Portable Object (Card, Smartphone, USB key…) and the equipment of the service provider, terminal or portable device. This high level of security needs a certain level of expertise to be correctly implemented in the equipment. CNA manages a set of technical documents to support to the developers such as technical notes available on the Calypso standard technical support website.

The main scope of Keyple is to allow developers to develop applications that communicates with Calypso portable objects, without being obliged to develop all the Calypso layer, that requires a lot of investment and expertise and big investments. So keyple is an abstraction layer that implement all the Calypso processing between a contactless secure element and a secure module into a terminal.

The operating systems and cryptographic calculations processed in both portable objects and Secure Access Modules are out of scope of keyple as the ticketing data model and fare calculations applications that will use the functions of keyple to access Calypso portable objects.
