Two-dimensional barcodes have been widely used both industrial environment, as a production process tracking method, and in commercial environment, as a product identifier. As a process tracker, each work piece has its own barcode to be scanned at every station along the production line. This allows real-time yield tracking of the entire production process, which provides a data basis for the process improcement. As a product identifier, the 2D barcode is also used for anti-counterfeiting and ensures the authenticity of products reaching end consumers. The invisible 2D barcode is marked with special laser-engraving equipment. The barcode is engraved inside the glass or sapphire material, which cannot be tampered with or removed. Different from visible barcodes, the invisible 2D barcode is not visible to human eye. It can only be read by certain barcode scanners. This quality can ensure no damage to the product cosmetics while keeping the whole production process traceability.
