For business processing and administrative purposes, companies often need to exchange documents for approval, either with internal employees or external parties. Reducing classic paper documents is an essential factor to increase efficiency. Nobody in today's business world wants or can wait a long time for the exchange of important documents, which is why documents are increasingly exchanged in electronic form today.

A trustworthy exchange between two or more people can be completed completely online in just a few seconds. This requires compliance with corresponding security aspects and the verifiability of legal validity. In order to ensure authenticity and integrity, documents should only be provided with electronic signatures, seals or time stamps.
