CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application No. 60/549,134, filed on Mar. 1, 2004, the entirety of which is hereby incorporated by reference into this application. COPYRIGHT AND LEGAL NOTICES [0002] A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyrights whatsoever. BACKGROUND OF THE INVENTION [0003] The invention relates generally to optically variable devices, such as diffractive optical variable images, and more particularly to optically variable devices including barcodes. SUMMARY OF THE INVENTION [0004] According to one embodiment of the invention, features and functions are provided for efficiently integrating a barcode with an optically variable device (OVD), such as a diffractive optical variable image (DOVI) indicia, on a substrate. [0005] According to another embodiment of the invention, features and functions are provided for creating an OVD, such as a DOVI, having a barcode on a substrate. The term "diffractive optical variable image" as used herein may refer to any type of holograms including, for example, but not limited to a multiple plane hologram (e.g., 2-dimensional hologram, 3-dimensional hologram, etc.), a stereogram, and a grating image (e.g., dot-matrix, pixelgram, exelgram, kinegram, etc.). [0006] According to another embodiment of the invention, a method is provided for creating an OVD, such as a DOVI, having a 3-dimensional barcode on a substrate, wherein each bar of the barcode includes a front portion, a back portion, and side-walls. The characteristics of the bars of the 3-dimensional barcode provide a proper reflection and/or refraction of a light, thereby enabling or improving a scannability of the barcode. In one embodiment, the surface area of the front portion of the bar is larger than the surface area of the back portion of the bar. In another embodiment, the edges of the bar are sharpened to a pre-determined sharpness. In yet another embodiment, the side-walls are tapered or slanted toward a central axis of the bar. In an additional embodiment, the bars are shortened to a pre-determined depth. [0007] According to another embodiment of the invention, a method is provided for creating a barcode and an OVD, such as a DOVI, on a first substrate (e.g., plastic, metal, etc.), said OVD embossed on said first substrate, said barcode including a first portion and a second portion, wherein said first portion of said barcode is embossed on said OVD and said second portion of said barcode is embossed or printed on a second substrate (e.g., a white plastic substrate for background, etc.). In one embodiment, said second substrate is embossed on said first substrate. In some embodiments, said second portion of said barcode is etched on said second substrate (e.g., a white plastic substrate for background, etc.). [0008] According to another embodiment of the invention, a method is provided for creating a plurality of barcodes and an OVD, such as a DOVI, on a first substrate (e.g., plastic, metal, etc.), said OVD embossed on said first substrate, said plurality of barcodes including a first barcode and a second barcode, wherein said first barcode is embossed on said OVD and said second barcode is embossed or printed on a second substrate (e.g., a white plastic substrate for background, etc.). In one embodiment, said second substrate is embossed on said first substrate. In another embodiment, said second barcode is etched on said second substrate (e.g., a white plastic substrate for background, etc.). In some embodiments, a first barcode is scannable only at a first pre-determined angle and a second barcode is scannable only at a second pre-determined angle, wherein the first and second pre-determined angles are angles between an axis of a scanner and an axis of one of the first and second barcodes. [0009] According to another embodiment of the invention, a method is provided for creating a plurality of OVDs, such as DOVIs, on a substrate (e.g., plastic, metal, etc.), each of said plurality of OVDs including an unique indicia, for example, a barcode indicia, said method comprising simultaneously embossing said plurality of OVDs on said substrate (e.g., plastic, metal, etc.), separating said each of said plurality of OVDs along with its corresponding substrate portion from the each other OVD, and attaching said separated OVD to a product (e.g., credit card). [0010] According to an embodiment of the invention, an optically variable device is provided that includes a first bar code. The first bar code is rendered in the optically variable device based on a second bar code, wherein the second bar code is a three-dimensional bar code including a plurality of bars each having a front portion, a rear portion, and sidewalls formed therebetween, wherein the distance between the front portion and rear portion of each bar of the second bar code is less than the height and width of the front portion of the respective bar of the second bar code. [0011] In another embodiment of the invention, the distance between the front portion and rear portion of each bar of the second bar code is less than half of the width of the front portion of the respective bar of the second bar code. [0012] According to another embodiment of the invention, the optically variable device is contained within a carrier, and the first bar code comprises information associated with an object to which the carrier attaches. [0013] In another embodiment of the invention, the information encodes a global trade identification number. [0014] According to another embodiment of the invention, an optically variable device is provided that includes a first bar code, wherein the first bar code is rendered in the optically variable device based on a second bar code, wherein the second bar code is a three-dimensional bar code including a plurality of bars each having a front portion, a rear portion, and sidewalls formed therebetween, and wherein the front portion of each bar of the second bar code has a first area and the rear portion of the respective bar has a second area smaller than the first area of the respective bar. [0015] In another embodiment of the invention, the sidewalls of each bar of the second bar code are tapered. [0016] According to another embodiment of the invention, the optically variable device is contained within a carrier, and the first bar code comprises information associated with an object to which the carrier attaches. [0017] In another embodiment of the invention, a machine readable symbol is provided that includes a first portion and a second portion. The first portion of the machine readable symbol is rendered in an optically variable device, wherein the optically variable device is contained within a carrier associated with a substrate. The second portion of the machine readable symbol is provided on a surface associated with the substrate. And the first and second portions can be read as a single machine readable symbol. [0018] According to another embodiment of the invention, the first and second portions include bar codes. [0019] In another embodiment of the invention, the second portion encodes information that supplements information encoded in the first portion. [0020] In another embodiment of the invention, the first and second portions include linear bar codes. Continue reading...
