What is Currency Detector ?

Currency Detector is a kind of machine that can 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.

Development history：

The cash counter is mainly used to count, identify and sort cash. It is widely used in various financial industries and various enterprises and institutions with cash flow. It first appeared in Wenzhou in the 1980s. It is accompanied by the emergence of counterfeit banknotes. It is the product of the market and private crackdown on counterfeit banknotes. Up to now, the development of cash counting machine has experienced three times.

The first stage is from the 1980s to the mid-1990s. The cash counter in this stage is mainly produced in small workshops, mainly distributed in Wenzhou, Zhejiang and Shanghai. The characteristics of the note counter in this period are that the mechanical function is greater than the electronic function, which can be counted simply, and the anti-counterfeiting ability is limited. It mainly uses the mechanical principle to count the notes for small-scale production.

The second stage is from the mid-1990s to the beginning of the world. At this stage, the banknote counter has been produced on a large scale, and a large number of large enterprises specializing in the production of banknote counter have emerged, including Xinda banknote counter of RMB publishing and distribution group, KANGYI banknote counter of Guangzhou KANGYI Electronics Co., Ltd., Wolong banknote counter of Foshan Wolong Electronics Co., Ltd., Zhongshan Baijia banknote counter and other leading enterprises, as well as institutions and departments specializing in the research of banknote counter. At this stage, leading enterprises began to pay attention to the identification and sorting of banknotes and serve ATM terminal machines. During this period, the shape of the cash counter became smaller, the machine became more stable, and the intentional brand sales began.

In the third stage, China’s cash counter has begun an era of digital, electronic and mechanical combination. During this period, due to the stability and maturity of the cash counter technology, there were many cash counter brands with OEM production and entrusted production in the market, and the market showed a situation of many, chaos and corruption. The leading enterprises in the early development mainly go to bank customers, which seems to be distinguished from those stall machines in the market.

At present, the cash counter on the market mainly uses fluorescence, infrared, penetration, safety line and magnetic tools to identify, count and sort the RMB. At present, the functions of cash counting machines in the market are almost the same, and the prices range from 300 to 2800. Most of the low prices are OEM and commissioned production machines, while most of the high prices are manufacturers (of course, not absolute). The main difference between them is that the manufacturer has a large number of researchers and product development costs, high quality of machine parts, high service life and high-quality after-sales service.

On November 12, 2015, the fifth set of RMB 100 banknotes of 2015 edition was officially issued, and the new banknote detector developed by Nanjing University of technology was unveiled. The new banknote detector can be described as a “golden eye”, which can not only identify “half true and half false” banknotes, but also track the whereabouts of banknotes. [1]

Professor Yang Jingyu of the computer school of Nanjing University of technology introduced that the counterfeit detection technology of the cash counter has changed from magnetic detection to image detection, and the detection methods have been upgraded from 5 to 11. “In addition to detecting the magnetism in the metal wire, you can also compare each figure on the banknote with the sample, and the recognition rate of counterfeit banknotes can reach 99.9%.” [1] “If all the cash detectors are networked, you can track the track of each note.” Hu Gang, for example, the identification and networking of Guanzi numbers can play an unimaginable role in anti-corruption, arrest and flight. For example, bribes can be traced to the source and flow of each stolen money by the word number. If we grab the bank, the ID number of the money will be recorded. Once it is used, it will automatically alarm.

Mechanical classification：

1. Portable handheld cash detector

Portable handheld laser banknote detector is a kind of RMB banknote discriminator whose appearance is about the size of mobile phone. Its appearance requires short, small, light, thin and humanized design concept. In terms of function, it requires the characteristics of diversified functions, high accuracy and energy saving. Therefore, a real portable handheld laser banknote detector should be an electronic product with good stability and high scientific and technological content.

The portable handheld laser banknote detector is small and beautiful. The inspection function is mainly based on laser technology, supplemented by infrared and fluorescence inspection. The external 4.5 ~ 12vdc-ac power supply has no polarity input port. It is more convenient to use external power supply. When using the external power supply, the internal circuit automatically converts the internal and external power supply without worrying about the safety and energy loss of the internal battery. In addition, this product is equipped with internal battery reverse connection protection; Overvoltage (15V), undervoltage (3.5V) of internal and external power supply, overcurrent (800mA), short circuit and other protection functions of load. After the protection function is started, completely turn off the power supply to protect the power supply and prevent further damage to the instrument.

2. Portable desktop banknote detector

Portable desktop laser banknote detector is generally large in size, which is similar to static desktop banknote detector. The difference is that the product can use dry battery or only dry battery as instrument power supply. Easy to carry. It is similar to the desktop static laser banknote detector in function.

3. Desktop static banknote detector

Desktop static banknote detector is a common banknote detector with a volume equal to or slightly larger than that of portable laser banknote detector. Its functions are generally magnetic inspection (magnetic inspection of magnetic code and safety line), fluorescence inspection, optical general inspection, laser inspection, etc. there are many kinds of functional expression, which is directly related to the manufacturer’s understanding of banknote detector technology and its plan for product cost. In particular, in order to seize the market or make huge profits again, some manufacturers reduce the functions of the products, or process the products with the simplest circuit and technology and directly consume them to the market, resulting in the proliferation of the banknote detector market. It has affected the stability of the whole banknote detector Market and brought a lot of trouble and losses to consumers.

The desktop static laser banknote detector has an incomparable combination of functions of similar products. It adopts laser inspection, optical general inspection, fluorescence inspection and infrared inspection as the main inspection functions of the product, and the external special banknote inspection purple lamp tube. The product has the functions of sound (voice) light false alarm, delayed sleep and so on.

4. Desktop dynamic banknote detector

The desktop dynamic laser banknote detector is an electric non counting laser banknote detector, which does not necessarily set the counting function in function. It is a variant of the desktop static banknote detector, but because it involves the electric mechanism, the design of its circuit and movement are more complex. The desktop dynamic laser banknote detector has the functions of automatic banknote feeding, automatic return of false banknotes and automatic separation of true and false banknotes. In terms of inspection functions, laser inspection, magnetic inspection (magnetic coding and safety line inspection), optical general inspection, fluorescence inspection, infrared inspection and engraving image characteristic inspection and other inspection functions can be used to accurately detect all kinds of counterfeit money, which can be said to be the real nemesis of lifelike counterfeit money and piecemeal counterfeit money.

In the circuit, in addition to the unique full bridge isolation filter power supply without grid interference in the power supply part, the desktop electric laser banknote detector adopts intelligent processing circuit in the realization of various functions, so as to make the performance of the product more stable and reliable. The desktop dynamic laser banknote detector works in the range of 85 ~ 320v mains voltage. The maximum power consumption is 8W. Its banknote inlet is located above the instrument, and the true and false banknote outlet is located in the front and back of the instrument. When checking banknotes, you only need to turn on the power supply. After hearing the voice advertisement and seeing the light of the power indicator, you can put the banknotes from the upper banknote inlet (the front of the banknotes is upward). After the instrument detects the banknotes at the warehouse opening, start the rotating mechanism and send the banknotes to the machine warehouse for inspection.

5. Laser cash counter

The laser cash counter is realized by adding the laser inspection function to the previous generation of the cash counter (except the image scanning laser cash counter). For other functions, please refer to the relevant articles on the working principle of the cash counter. Since the banknote detector can only be used as an auxiliary tool for banknote identification, when identifying banknotes, in addition to using the banknote detector to check various anti-counterfeiting marks and paper characteristics that cannot be observed under general conditions, we should also rely on our own careful observation of banknotes to determine the authenticity of banknotes.

Counterfeiting technology

After multiple anti-counterfeiting, the six identification methods can identify the banknotes with clip, duplicate, continuous and incomplete banknotes – missing corner, half sheet, sticky paper, graffiti, oil stain and other abnormal states. Combined, they can be upgraded to a fully intelligent banknote counter with denomination summary.

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

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 forgery detection: according to the characteristics of RMB, coupled with penetration forgery detection mode, it can increase the ability to identify all kinds of counterfeit currencies;

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

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 with 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. Detection and detection of counterfeit by digital quantitative qualitative analysis: 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.
