The DAFÜR GmbH provides solutions for data transmissions for local and long distance services. This can be products for local computer networks (Local Area Network, LAN) or for dial- and leased line services of the ISDN.

This can be done by many others as well.

Especially the setting to work of the frontend IRENE, i.e. at a company for payment transaction authorisation, a lot of different and new requirements have to be managed in a way of prototyping. This can only be managed reasonably by engineers with a long standing experience.

This can be done only by a few others.

And when you than have to go into deep because data transmission protocols aren´t even kept accuratly by global acting companies and the detailed flowing has to be found out, than you need to have access to the development, directly, without any "hotline" or 8000 km atlantic ocean in between.

This can be done by only a handfull.

DAFÜR GmbH is one of those.
