A tamper monitoring article and system, and an associated method of making, installing and using the article and system. The article has an elongate body portion. The body portion has a first end portion that adheres to a second end portion, if present, or to a substrate. The article also includes a pathway structure that runs along or throughout the body portion and can conduct energy, such as light or electricity, along its length. A monitor communicates with the pathway structure and detects a change in the energy being conducted thereby. A change in the energy is indicative of a change in a conductive property of the pathway structure caused by, for example, manipulation of the body portion and the pathway structure that is disposed therein or thereon. The monitor can then signal, or respond to a request signal, and provide information that such manipulation has occurred.

The invention claimed is: 1. A tamper monitoring article, comprising: an elongate body portion having a first end portion and a second end portion, the first end portion being adherable to the second end portion or to a substrate; a pathway structure extending along the body portion that is responsive to manipulation by indicating that manipulation has occurred, whereby the article can be secured to the substrate and can indicate whether the body portion has been manipulated; and an embossable layer disposed on or in the first end portion; wherein the embossable layer is physically embossable, the embossable layer is responsive to pressure from a sealer surface by conforming to a texture of the sealer surface, whereby the embossable layer has a corresponding texture after contact with the sealer surface; and wherein the embossable layer campuses a thermochromic ink that responds to the heat present in a heat sealing operation by changing colors, opacity, conductivity, or like property. 2. The article as defined in claim 1, wherein the corresponding texture on the embossable layer forms a pattern that is difficult to replicate. 3. A tamper monitoring article, comprising: an elongate body portion having a first end portion and a second end portion, the first end portion being adherable to the second end portion or to a substrate; a pathway structure extending along the body portion that is responsive to manipulation by indicating that manipulation has occurred, whereby the article can be secured to the substrate and can indicate whether the body portion has been manipulated; and an embossable layer disposed on or in the first end portion; wherein the embossable layer is magnetically embossable. 4. A system for monitoring tampering, comprising: a body portion configured to secure to an item to be monitored for tampering and having a free end portion, the end portion comprising a plurality of layers that are substantially adjacent to each other to define a multi-layer composite, the plurality of layers comprising: a facestock layer, an adhesive layer supported on the facestock layer comprising a heat seal adhesive or a heat activatable adhesive, and a frangible layer, embeddable layer or a de-laminatable layer supported on the facestock layer. 5. The system as defined in claim 4, wherein the embeddable layer supports a monitoring subsystem comprising a conductive pathway structure and an RFID in communication with the pathway structure. 6. The system as defined in claim 4, wherein the frangible layer responds to manipulation of the body portion by changing appearance or properties. 7. The system as defined in claim 4, wherein the de-laminatable layer comprises two coextruded colored layers that are substantially adjacent to and coextensive with each other along an inner surface, and two adhesive tie layers, wherein each tie layer is substantially adjacent to and coextensive with a respective one of the colored layers, and the tie layers have an adhesive strength that is increased relative to an inter-laminar strength of the colored layers. 8. A security strap comprising: a data-carrying medium; an outer coating encircling the data-carrying medium; wherein the coating has plural transverse ridges protruding therefrom; and wherein the data-carrying medium and the coating are co-extruded in a concentric fashion. 9. The strap of claim 8, wherein the ridges are angled ridges. 10. The strap of claim 9, wherein the ridges are configured to engage a surface, to prevent relative motion of the strap and the surface in one direction. 11. The strap of claim 8, wherein the coating has an axial groove therein. 12. The strap of claim 11, wherein the axial grove is configured to engage a protrusion from an opening. 13.
