Abstract:

A method and apparatus for theft identification of articles, such as, machines and equipment employs one or more miniature, coded portions or disks, each disk in the form of a thin film bearing preassigned data which is photo optically reduced on the film so as not to be readable with the naked eye, and at least partially severed from the film so as to facilitate application to an article. The disks may be placed on or buried in the articles at different locations known only to the owners as well as being placed at other random locations and are composed of a material not discernible by remote locating means thereby making it virtually impossible for unauthorized persons to locate and remove the disks from the equipment.
