Abstract
A method of fabricating a tag or marker carrying or intended to carry a magnetic code is described. The method comprises applying a particulate magnetic material to a surface region of the tag by a printing or transfer process. The particulate magnetic material is generally deposited in the form of discrete elements or indicia. A tag thus produced can be coded magnetically by magnetising the elements or indicia, e.g. with a permanent magnet. This provides a very versatile and relatively rapid means of generating coded tags or labels virtually without limit on the variety of codes which may be adopted.
