The invention relates to security features, preferably tear-off strips or strings, for identifying the authenticity of products by the producer or authorized controlling bodies. The inventive security features consist of several different components, coding means and electrically conductive layers, whereby all of these are attached in varying order to a supporting substrate. Layers of known electrically conductive polymers are used. According to the invention, these security features are presented in the form of tear-off strips that, for example, are press molded, adhered or sealed to a packaging. These security features pose insurmountable technological hurdles to counterfeiters. |
