A device and method for direct recording of prints of a rolled finger provide optimal recording of rolled fingerprints by a user by visually displayed influencing of the rolling movement during the roll process. By direct recording of the rolled finger by a layer body with a sensor layer of two-dimensional matrix of sensor elements and a parallely opposite support surface on which the finger can be rolled, the distance between the sensor layer and the support surface is less than five times the mean distance between adjacent sensor elements. A light source with lighting elements that can be controlled individually or in groups to generate light portions through the support surface as visible patterns for user information with spatial and temporal reference to the rolling finger. An electronic control unit controls the light source in different areas of the support surface to generate a pattern variable over time.
