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.

Abstract

The invention discloses an invisible bar code, which is bar code printed with infrared or ultraviolet anti-fake material, which has sky high anti-fake performance, and it is difficult to be forged. The invention also discloses an identification system which includes: infrared or ultraviolet semiconductor laser, bar code scanner and computer system. The bar code scanner is integrated with photoelectric conversion system, amplifying and plastic system and decoding system.

Description

【Technical field】 [0001] The present invention relates to an invisible barcode and its identification device. 【Background technique】 [0002] In recent years, with the continuous popularization of computer applications, the application of barcodes has been greatly developed. The barcode can mark the country of production, manufacturer, commodity name, production date, book classification number, mail start and end point, category, date and other information, so it can be obtained in many fields such as commodity circulation, book management, post and telecommunications management, and banking system. widely used. [0003] The barcode is composed of bars and spaces with different widths and different reflectances, compiled according to certain coding rules, and used to express a set of digital or alphabetic symbol information. A pattern of parallel lines arranged with spacing. Common barcodes are composed of black bars (referred to as bar spaces) with greatly different ref...
