Abstract:
A method of marking and tracking goods from place of manufacture to place of final distribution, the method comprising the steps of:(a) providing a control computer to control and enable a host computer by providing an allotment of encoded symbols indicating said place of final distribution; (b) enabling said host computer to direct a printer at said place of manufacture to print said encoded symbol on said goods forming marked goods; (c) enabling said host computer to direct a second printer at said place of manufacture to print said encoded symbol on a package containing a plurality of said marked goods thereby forming a marked sized package of marked goods; (d) scanning said marked goods and said marked sized packages with a field reader illumination source which provides light which is absorbed by a first compound within dye used to print said encoded symbol and wherein said first compound subsequently forms a first emission; (e) capturing said symbol imprinted thereon by detecting emissions from a second compound within said dye which is excited by absorption of said first emission; and (e) verifying the authenticity of said symbol.
