The invention relates to a method for transferring applications to a different platform, which prevents creation of GUI definition at the target platform. The magnet brush contacts and thereby develops a latent image formed on an image carrier. If the database entry shows an association between the first digital identity and the second digital identity, the digital identities are valid and an indication of the validation of existence of association between first digital identity and second digital identity is made by the authenticating device. The assembling mechanism includes a flexible connecting part and a driving part. A further material processing device may include a material processing system directed along a predetermined path. One or more additional communications units may communicate over an asynchronous link established between the master and additional units using remaining time slots.
