So far, digital business models such as pay per use have rarely been used for complex products, processes, and services in production technology. One reason for this is a lack of information on the lessor side, especially about the necessary and sensitive production data of the machine operators. This inhibits knowledge-based pricing and results in business risks. This paper presents a new information path by means of a digital notary – a technical solution for secure, condition-based pricing – to resolve this deficit.
