Die Quadriga‐Mobile‐App ist ein Hilfsmittel zur Inventarisierung Ihrer Inventargegenstände, den so genannten 'Komponenten'. Sie können sehen, in welchen Räumen sich welche Komponenten Ihres Inventars befinden, und im Rahmen von Bestandskontrollen feststellen, welche Komponenten fehlen oder in andere Räume umgestellt wurden. Die App arbeitet zusammen mit der PC‐Anwendung Quadriga‐IT. In dieser Anwendung werden die Daten zu den Komponenten bereitgestellt und per E‐Mail versandt. In der App können Sie die per E‐Mail erhaltenen Daten dann importieren und mit der Inventarisierung beginnen. Nach Ihrer Bestandskontrolle schicken Sie die Ergebnisse Ihrer Arbeit per E‐Mail zurück und werten Sie mit Quadriga‐IT aus.
