Standard and technological centrepiece: VDV core application and (((etiCORE
VDV core application (VDV-KA): This is the name of our open data and interface standard for electronic ticketing and electronic fare management (EFM) in public transport. The VDV-KA is the technological centrepiece of the electronic ticketing system (((eTicket Deutschland, on which the EFM systems introduced throughout Germany by transport associations and companies are based.
We are currently developing version 3 of the VDV core application. To ensure that international manufacturers of components and systems as well as transport companies abroad can also work with our open standard in future, the new version will also be published in English - and will have an international name: (((etiCORE

The development of the ticketing standard
From the initial idea in the early 2000s to the birth of (((etiCORE.
Download guide (((etiCOREFunction and expansion stages of the VDV core application
If you are a transport company working with the VDV-KA, you can decide for yourself which range of functions you want to use or offer your customers. The basis for this is a participation agreement, which primarily regulates organisational issues so that all connected systems can work together on an equal footing and automatically.
From a technological point of view, the respective user media (chip cards, NFC or RFID-enabled user media such as smartphones) of (((eTicket Deutschland support all existing expansion variants, even if only certain functions should be activated in the respective area of application.

We published VDV KA Release 1.12.1 at the end of January 2025. The release has been available for download in the ASM tool since then. All VDV KA specifications are available there free of charge to (((eTicket Germany participants.
The new version of the VDV KA is currently under development. It will be called (((etiCORE and will also be published in English. You can find the current release plan at .
You can also download the bilingual glossary for the VDV-KA 1.x and (((etiCORE specifications here.

The future of the VDV core application is called (((etiCORE
(((etiCORE stands for everything that characterises us - from the three brackets of contactless payment to its core. The internationally understandable pronunciation also goes hand in hand with the simplification of the standard: (((etiCORE is an improved and, above all, leaner version of the VDV core application.
With (((etiCORE, certificate extensions ensure that user media and SAMs can be used for much longer. This saves costs. In addition, the ordering and distribution of keys is largely eliminated, which reduces the complexity of handling. In the application, the speed of the issuing, control and recording processes increases significantly.

Together we design (((etiCORE
The VDV core application 1.X will remain the VDV core application until it is completely switched off and archived in 2031. (((etiCORE will become active in 2026. From this point onwards, we will operate both the VDV core application and (((etiCORE in parallel.
We are already making working documents relating to (((etiCORE available on our collaboration platform (((efi. There you can ask questions and discuss with us, manufacturers and employees of transport companies in the forum. In this way, the next generation of the eTicket standard will benefit from the operational experience of the entire public transport sector and the industry involved.
