Abstract (en)

The object is marked using an assortment of colored elements wherein each colored element represents a specific position in a binary number. A series of colored elements is combined to represent a binary number. The series of colored elements is then used to mark the object. For example, the series of colored elements can be incorporated into a flowable material or adhered to an individual object to be identified. Each colored element can include a single color, or a plurality of colors. Preferably, each colored element comprises at least two distinguishable colors. More preferably, each colored element comprises no more than two distinguishable colors.
