ABSTRACT:
The security of articles, and particularly articles in transit, is checked by detecting the status of a magnetic strip attached to the articles at a strategic location when the strip is subjected to an electromagnetic field which causes the strip to substantially saturate magnetically, the status of an improper strip, that is to say, a strip whose electromagnetic properties differ from those of a proper strip as a result of physical modification or disparity, being reflected in the nature of the electromagnetic field emanating therefrom, detection of the status of that field providing an indication of whether the strip is proper or not. The same principles can be applied to the coding of articles for validation of identity or authenticity.
