The invention relates to a security document comprising at least one security element. The security element is formed in such a way that it can be determined by means of human touch. As a result, surface characteristics of various surface areas can differ in such a way that the shape and the size of said different surface areas can be determined by human touch. Another possibility is to provide the substrate of the security document with correspondingly formed holes which can be identified by means of human touch. The invention also relates to a combination of various tactile security elements of said type. |
