Embodiment 1
[0013] The invention uses the infrared anti-counterfeiting material described in Patent No. ZL 00113404.3 to print barcodes as product anti-counterfeiting marks.
Embodiment 2
[0014] Example 2 Infrared barcode recognition device
[0015] like figure 1 As shown, the infrared anti-counterfeiting identification device of the present invention includes an 800nm-1000nm infrared light semiconductor laser 1 with a product model of HLD9805-D produced by Shenzhen Huale Electronics Co., Ltd., a barcode scanner 2 is an American Xunbao SYMBOL type and a computer system 3, The barcode scanner is electrically connected to the computer system. The barcode scanner integrates a photoelectric conversion system, amplifying and shaping system, and a decoding system. The infrared light semiconductor laser is used to illuminate the barcode, so that the infrared barcode shows color stripes. The displayed barcode information is determined by the barcode. After being read by the scanner, it is received by the photoelectric conversion system, and then the information is read out by the computer system and the authenticity is identified by the amplification, shaping and decod...
Embodiment 3
[0017] The ultraviolet anti-counterfeiting material of the present invention is the invisible fidelity fluorescent material described in Patent No. ZL 951117918.7, which is used to print barcodes as product anti-counterfeiting marks.
