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.
