According to this, services must be findable, accessible and usable for people with disabilities in the generally accepted manner, without particular difficulty and, in principle, without outside assistance. This means 

  • Information on the accessibility of the service must be provided and identification, authentication, security and payment functions must be barrier-free.

4. status of compatibility with legal requirements

  • Simple preparation of our content: Where possible, we use easy-to-understand text to describe our products and services. Technical terms are explained in a practical and understandable way at the appropriate points so that users without specific prior knowledge can also understand the relationships presented.
