To ensure that IT solutions are adequately designed and programmed to be barrier-free for all those affected, the BITV criteria are a helpful tool.

BITV stands for Barrier-free Information Technology Ordinance and is a bit dry as a set of rules, but extremely important. We’ll try to simplify it a little here, because these criteria must be met if you want to call yourself or your IT product “barrier-free” or have it certified as such. Everything else is just “barrier-free” – also nice, but in many cases not enough. So if you want to venture into barrier-free websites, you will find help here – through information or gladly through active participation by us. Our IT solution for better compatibility of family and work is just about to be certified. Therefore, we use this example to show how the project is progressing and how we have solved one or the other.
