Abstract
There is proposed a security document comprising a security element, wherein the security element is of such a configuration that it can be determined by means of the sense of human touch. For that purpose either the surface nature of various surface regions can be selected differently so that the configuration and size of the different surface regions can be determined by the human sense of touch. Another possibility is for the substrate of the security document to be provided with suitably shaped openings which can be identified by means of the human sense of touch. A combination of different tactile security elements of that kind is also described.
