Problems solved by technology

The disadvantage of this type of carbon paper is that this technology only detects whether there are fluorescent materials in the handwriting. This technology is easy to be imitated. It only needs to be mixed with fluorescent powder when making the carbon paper, and it is easy to be forged by ordinary manufacturers.
The technologies listed above for anti-counterfeiting carbon paper have their own advantages and disadvantages, but they are still relatively easy to be imitated

Abstract

The invention includes manometric copying paper, carbon free copying paper, magnetic memory material and detector. Magnetic memory material as a well magnetic metallic oxide is capable of storing, inputting and saving electromagnetic cryptographical information. Detecting method is as following: non-contacting type detector scans handwriting on paper; converted memorized cryptographical information in magnetic memory material is magnified; comparing detecting and discriminating cryptographical information by IC chip; informing tested result to alarm buzzer. Advantages of the invention are good effect of anti false and duplicable suitable to finance, insurance, tax affairs and custom etc.

Description

technical field [0001] The invention relates to carbon paper, in particular to anti-counterfeit carbon paper with memory codes, a detector for detecting carbon writing written or printed on the carbon paper and a detection method thereof. Background technique [0002] At present, the anti-counterfeiting technology of carbon paper has the following main forms: 1. It is made of watermark paper, which is similar to banknote paper; 2. It is made of textured coated paper; 3. It is made of colored or colorless fluorescent anti-counterfeiting materials, etc. Chinese Patent (Application No.) 94116732.1 Carbonless copy paper with latent image, it adds a latent image forming process in the process of manufacturing carbonless copy paper base paper, this process can add a watermark for setting logo graphics on the paper machine network rollers to form watermarks on wet paper pages; or add embossing rollers in the drying process of papermaking to press out watermark-like graphics on carb...
