ABSTRACT:
An identification marking system for objects involves giving each object its own electronic name tag. The electronic name tag can be specific amount of ferrite material that has been added to the object. An electronic reader system then measures the effect said object has on an identifying circuit as the object passes in close proximity to the identifying circuit. The measured effect is then compared to a pre-established value. The value on the electronic reader system becomes the electronic name tag for this specific object. It is not necessary to add ferrite to the objects to be identified. Most materials have a measurable effect on a variety of electronic circuits. An electronic name tag may well be established by simply placing an object in the vicinity of a particular circuit and measuring the results. The results are then compared to a pre-determined set of values. The results of this comparison will provide an electronic name tag for this specific object.
