Rarely performed documentation tasks usually require support for the user so that the data is recorded both completely and correctly. The broad market penetration with mobile devices like smart phones provides new possibilities for giving support for these kinds of tasks. This paper focuses on one particular widely-used instance of such a documentation task, namely the European Accident Report (aka Agreed Statement of Facts on Motor Vehicle Accident). Firstly we discuss the advantages of media-break-free processing of all the relevant data. Secondly we present the client part of the application, which allows on-site documentation by any of the parties involved. Both application parts can be used for processing claims in the back office. We highlight the possibilities of service-chain integration, the digital accident file generated by using this solution and the resultant advantages for media-break-free processing of claims.
