Mr Winfried Honecker equensWorldline SE Germany

Dr. Winfried Honecker has over 20 years’ experience in the Poseidon OLTP product area at equensWorldline GmbH. Thanks to his longstanding experience in the field of network operations, he is now responsible for the development and implementation of concepts for new topics.

In autumn 2016, he was made project leader at equensWorldline GmbH for establishing ZVT-H.

The ZVT-Host-Schnittstellen-Anwender e.V. Advisory Board

Decisions concerning the maintenance of the interface result from transparent decision-making processes and – as is usual for the internal procedures of standards organizations – must be based on a consensus opinion of the members, but without a veto right of any single member. A ZVT-H Advisory Board was established to evaluate requests and requirements, and extend the interface for future needs. The Advisory Board plays the principal role in coordinating the work, evaluating members’ extension requests, and coordinating the implementation of changes.

Under the statutes and association’s charter, ZVT-H members alone have the right to request changes to the specification, in particular extensions, clarifications, corrections and similar additions to the ZVT Host Protocol.

The association does, however, also make its decision-relevant information publicly accessible on this website and communicate its decisions and updates here.

The Advisory Board consists of five people who are elected from ZVT-H members, in each case, for a three-year tenure.

The ZVT-H Advisory Board current consists of the members:

Karl-Heinrich Funck (Advisory Board Chair)
PAYONE GmbH
Stefan Dimitrov (Advisory Board Member)
PayTec AG
Uwe Liegl (Advisory Board Member)
CCV Group B.V.
Peter Ulbrich (Advisory Board Member)
Verifone GmbH
Kai Martin (Advisory Board Member)
Feig Electronic GmbH
