摘要
A security device having at least one durable tactile marking (16) in the form of one or more relief structures is provided. The one or more relief structures are selected from the group of elastically deformable relief structures, relatively compression-resistant relief structures, and combinations thereof. Also provided is a fibrous or non-fibrous sheet material (10) with at least one durable tactile marking, which is suitable for use in making secure and non-secure documents or labels. The tactile marking (s) is applied directly to a surface of the sheet material, or is provided by way of the above-described security device (s), which is mounted on a surface of the sheet material and/or at least partially embedded therein. The durable tactile marking (s) serves to provide a visually challenged person with information concerning the type and/or value of the secure or non-secure document or label.
