IDENTIFICATION LABEL AND METHOD OF LABELLING AN OBJECT

摘要

An identification label consisting of a matrix of solidified plastic carrying within it a plurality of ramdomly positioned visually distinguishable beads. The label is formed by mixing the beads with the plastic in a fluid state and then solidifying the plastic. The position of the beads in the solidified plastic is read and recorded as an identification code, for instance by recording the position of a sequence of beads above or below a line representative of the ones and zeros in a binary code. The binary code can be read and stored in a database as an identifier of an object to which the label is attached. Two or more labels may be attached to an object, one hidden and one visible, with the two codes being recorded for that object. The label can be used as a security identifier for, for example, banknotes.
