Digital contact tracing saves paper and time

Due the Covis-19 pandemic your customers would have to print, hand over and fill out many forms. With 2FDZ – the pioneers of digital contact data acquisition – you can have this done easily and securely online.

Sounds complicated, but it’s easy.

  • You can concentrate on your customers.
  • You need less paper.
  • There is no need to pick up and shred files.
  • And all of this is also data protection compliant.

Our web application ensures smooth documentation in the background. 2FDZ works without installation and without additional hardware. As a web application, the data is transmitted in encrypted form and stored on our security server for this one purpose only.

Just print two pages. Finished.
