The invention comprises a method and system for preventing the unauthorized removal of paper rolls, such as cash register receipt paper rolls used by retailers, as well as the anti-theft paper roll and methods of preparation therefor. The method comprises affixing to the paper roll an electronic sensor, wherein the sensor emits a detectable signal; and detecting the presence of the sensor when it passes through or near a detection point at the retailer's location. In one embodiment of the invention, the sensor is an adhesive strip, affixed to the core of the paper roll, wherein the core of the paper roll comprises a flat surface integrally formed therein, onto which the sensor is affixed.

1. A method for preparing an anti-theft paper roll, comprising: manufacturing a core onto which paper is wound to produce the paper roll, wherein the core is a hollow cylinder comprising an interior surface having a circular inside diameter and an exterior surface having a circular outside diameter, between which surfaces is a core wall, and wherein the exterior surface further comprises a longitudinal flat surface integrally formed therein; selecting an electronic sensor, wherein the sensor produces a detectable signal, and wherein the sensor comprises an upper surface and a lower surface, and wherein the dimensions of the sensor do not exceed the corresponding dimensions of the flat surface of the core; affixing the lower surface of the sensor to the flat portion of the exterior surface of the core, and wherein when the sensor is affixed to the core, the location of the upper surface of the sensor does not exceed the circular outside diameter dimension of the exterior surface of the core; selecting a solid loading rod of a paper winding machine, wherein the rod has an outside diameter less than the inside diameter of the core, and wherein the hollow core is loaded onto the loading rod through the hollow region of the core, to permit winding the paper onto the core when the paper winding machine is activated; and winding the paper onto the core with the sensor affixed thereto. 2. The method of claim 1, wherein the difference between the outside diameter of the loading rod and the inside diameter of the core is at least 1/16 inch. 3. The method of claim 1, wherein the lower surface of the sensor further comprises an adhesive layer. 4. The method of claim 1, further comprising applying a layer of adhesive between the lower surface of the sensor and the flat portion of the exterior surface of the core. 5. A method for preventing the unauthorized removal of a paper roll from a retailer, comprising: affixing to the paper roll an electronic sensor, wherein the paper role comprises a core, having an exterior surface with a longitudinal flat surface integrally formed thereon, and wherein the sensor is affixed to the flat surface of the core, and wherein the sensor produces a detectable signal; and detecting the signal from the sensor when it passes through or near a detection zone at the retailer's location, thereby preventing unauthorized removal of the paper roll. 6. An anti-theft paper roll comprising a paper roll having an electronic sensor affixed thereto, wherein the paper roll further comprises a hollow cylinder core comprising an interior surface and an exterior surface, between which surfaces is a core wall, and wherein the exterior surface further comprises a longitudinal flat surface integrally formed therein, onto which the sensor is longitudinally affixed. 7. The anti-theft paper roll of claim 6 comprising a layer of adhesive between the exterior surface of the core and the sensor. 8. The anti-theft paper roll of claim 7, wherein sensor comprises an upper surface and a lower surface, and wherein the adhesive layer is integral to the lower surface of the sensor.
