Keypop developments follow the definitions of ticketing terminal API issued by CNA: , starting with an initial development in Java for each interface evolution, followed by a porting in C++. Keypop APIs are initially be versioned as a release candidate until a first implementation has been completed to validate the interfaces (e.g. on Eclipse Keyple).
Current work and future developments
- For the first quarter of 2025, we plan to release the Keypop C++ APIs (currently available as a release candidate) in stable version 2.x.
- During 2025, a new interface dedicated to the administration of a Calypso security module of the ‘OpenSAM’ type should be developed.
History of developments
The information on functional evolutions for each Keypop API version matches precisely those indicated in the ticketing terminal API development history. Here’s the development integration history for each interface by programming language.
