What is Money detector banknote detector? How to identificate Counterfeiting technology?

Banknote detector is a kind of machine to verify the authenticity of banknotes and count the number of banknotes. Due to the large scale of cash circulation and the heavy work of cash processing at the bank cashier counter, the cash counter has become an indispensable equipment.With the development of printing technology, copying technology and electronic scanning technology, the manufacturing level of counterfeit banknotes is getting higher and higher. It is necessary to continuously improve the counterfeit detection performance of banknote counting machine. According to the different movement tracks of banknotes, the banknote counting machine is divided into horizontal and vertical banknote counting machines. There are usually three ways to distinguish counterfeits: fluorescence recognition, magnetic analysis and infrared penetration. Portable banknote detector is divided into portable desktop laser banknote detector and portable handheld laser banknote detector.

Counterfeiting technology identification:
After multiple anti-counterfeiting, the six identification methods can identify the banknotes in abnormal states such as clip, duplicate, continuous and residual banknotes – missing corner, half sheet, sticky paper, graffiti and oil stain, which can be integrated into a fully intelligent banknote counter with denomination summary.

1. Magnetic forgery detection: detect the distribution of magnetic ink of banknotes, and also detect the RMB safety line of the fifth edition;

2. Fluorescent forgery detection: check the quality of banknotes with ultraviolet light and monitor them with photoelectric sensors. As long as there are slight paper changes, they can be detected;

3. Penetration counterfeiting: according to the characteristics of RMB, coupled with penetration counterfeiting mode, it can increase the ability to identify various counterfeit currencies;

4. Infrared counterfeit detection: advanced fuzzy recognition technology is adopted to effectively identify all kinds of counterfeit banknotes according to the infrared characteristics of banknotes;

5. Multispectral forgery detection: multispectral light source, lens array, image sensor unit array, control and signal amplification circuit and input and output interface formed by arranging led particles of different wavelengths into a matrix; The multi spectral light source and lens array form an optical path system, which is used to emit light and focus the reflected light on the RMB on the image sensor unit array. The multi spectral image sensor image analysis function is used to identify the authenticity of banknotes.

6. Digital quantitative qualitative analysis detection and counterfeiting: using high-speed parallel AD conversion circuit, high fidelity signal acquisition and quantitative analysis of ultraviolet light, counterfeit banknotes with weak fluorescence reaction can be detected; Quantitative analysis of magnetic ink of RMB; Fixed point analysis of infrared ink; Using the theory of fuzzy mathematics, some factors with unclear boundary and not easy to quantify are quantified, and a multi-level evaluation model for safety performance evaluation is established to identify the authenticity of banknotes.
