A system and associated method provide a marking of material to be applied to goods. In one embodiment, magnetic material is applied in a predetermined pattern. An accumulation of magnetic material in one orientation across the structured pattern may provide an automatically sensible value. Magnetically readable material may be provided as a predetermined, repeatable pattern, where the magnetic material is applied to a surface with a resolution in a range of at least 10,000 to 100 dots per inch. |
