Currently, the probability of encountering counterfeit banknotes is very high. Moreover, a fake can fall into the hands of almost anywhere. In this regard, most companies and firms decide to buy a banknote detector. Before making a choice, it is necessary to study the existing types of devices and the principle of their operation.
Means of protection of banknotes
A banknote detector is currently a mandatory attribute of any credit institution, financial institution and many retail outlets. This is easily explained by the fact that no one wants to receive simple pieces of paper instead of money, but at the same time, it is simply impossible to distinguish a fake without special equipment. If earlier the authenticity of a banknote could be determined only by a watermark, which was easily determined by the light, now the degree of protection is very difficult.
First of all, cotton or linen fibers are included in the composition of banknote paper to increase wear resistance. In addition to the main fabrics inside the money, there are fluorescent particles, watermarks, special elements, embossing, fibers, microprinting, combined pattern, perforation, security threads, kinegrams and holograms, as well as infrared protection zones.
A banknote detector is a device that scans banknotes and compares the received information with a programmed standard. If at least one of the parameters does not match, the device sends a signal to the operator. It can also reject counterfeit bills by placing them in a special pocket.
Types of appliances
All current banknote detectors are divided into two types. The first of these includes viewing devices (ultraviolet and infrared, as well as complex ones). The second type of detectors are automatic.
Viewing devices allow you to clearly see subtle or hidden signs of the authenticity of the banknote. However, the final decision must be made by the operator. As for automatic detectors, they independently select counterfeit banknotes, excluding the human factor. This is especially true in cases where workers are low-skilled. When using an automatic detector, the cashier may not be trained in counterfeit detection. Counterfeit banknotes will not pass through the machine.
UV detectors
Such devices until recently stood in almost every outlet. The banknote authenticity detector is equipped with a special lamp. It works in ultraviolet mode. UV rays hitting a banknote cause its fibers to glow in different colors.
Today, such detectors have become practically useless. Counterfeiters have already acquired the skills to counterfeit this security component. Despite this,ultraviolet detectors continue to be in stable demand. This is explained as follows:
1. Very low cost, starting from 100 rubles. Such a detector will not detect a well-forged fake. However, there is still a point in being at a retail outlet. The very fact of the presence of such a device in the hall is able to scare away the novice distributors of counterfeit banknotes. But experienced scammers will go to such a store.
2. The presence of this device is necessary for the sale of alcohol at the request of the licensing chamber. Excise stamps are checked on this machine.
3. UV devices are often purchased by veterinarians. They need them to detect lichen in dogs and cats.
UV detector selection
Models of these devices differ in power and the number of built-in UV lamps. One such device is the DoCash 531 banknote detector. The device has two upper UV lamps, the power of each of which is 6 watts. This strong source of ultraviolet rays makes it possible to effectively detect counterfeit banknotes in a well-lit room. The lower lamps are used to check watermarks, micro-perforations, as well as images on both sides of the bill.
The DoCash 531 banknote detector has a large and convenient viewing field, which is equipped with a ruler for determining the size of banknotes, the accuracy of marks located on the banknote, etc. This device is quite easy to operate.
This model will also help in the case when it becomes necessary to clarify the authenticity of a document. To do this, use the special slot on the back of the case.
Infrared detectors
Today, this type of counterfeit money recognition device is the most popular. The infrared banknote detector guarantees counterfeit detection. Fraudsters have not yet learned how to make such protection on their money.
The design of this device is quite simple. The cashier places the banknote under examination in front of the detector, which illuminates it with infrared LEDs. The rays are reflected from the banknote and pass through the light filter. Then they are captured by the camera, displaying the image of the banknote on a special display. At the same time, the cashier sees the banknote in the infrared range. Only a small fragment of his drawing is clearly visible on the genuine banknote. The fake is all over the place. An experienced cashier is able to check a whole stack of money very quickly by flipping through the bills in front of the detector.
With this device, you can check the authenticity of various documents that have IR protection. These are securities, passports, etc. Infrared devices are used at the cash desks not only of retail outlets, but also of various large companies.
Popular model
DoCash Mini infrared banknote detectors are in high demand. They take up minimal space and are equipped with an innovative desktop stand, reinforced with stiffeners.

Users are attracted by the simplicity of its design and simple operation, understandable on an intuitive level. It is also convenient that the device can be powered not only from the network, but also from the battery.
Complex devices
This banknote detector is able to check all existing types of money protection. In this device, IR and UV devices are combined in one housing. In addition, complex detectors include:
- lower regular and very good top illumination;
- test pencil;- magnetic head (checks magnetic banknote marks).
There are other options. That is why such devices have impressive dimensions. Their price is not the lowest either.
Banks must have complex detectors. Only in this case they will be able to check the various types of money protection. Is it worth it to have such devices of a trade organization? It is hardly necessary to overpay for a device that will not be used one hundred percent. But the choice is always up to the buyer.

- geometrical dimensions;- banknotes in white transmitted, reflected, and also incident oblique light.
The camera of such a detector gives a ten- and twenty-fold increase in the banknote image.
Automatic detectors
The use of devices of this kind does not require special knowledge from the operator. Such a detector performs the verification of the authenticity of banknotes in automatic mode. These devices are used where there is a need for frequent and quick banknote checks.
Automatic banknote detector is installed at the cash desks of supermarkets and shops, gas stations and banks. Such devices will equally qualitatively check the authenticity of any currency.

The Dors 220 banknote detector can operate in two modes. In the first of them - the main one - a genuine bill passes through a special slot to the output, and a fake one returns back to the receiving stream. If a fake is detected, the device displays a message on the screen, which indicates a detection error. For convenience, this data may be accompanied by sound.
The second mode of operation is designed to operate the device in a confined space. The machine returns all banknotes to the receiving tray, reporting a detection error with a sound signal and a record on the display.
The Dors 220 detector has the advantage of being able to easily access the path. This option is available thanks to the hinged lid. In addition, the machine is equipped with a system that allows the user to set the power saving mode byauto-off after a certain period of time.

Currently, PRO, Magner, Technology, Intellect, Dors banknote detectors are widely known in Russia. They are in constant demand. Detectors from SPEED and Spektr-Video-MT receive the most criticism. Most users recommend to refrain from buying them.
Repair
Fixing the breakdown of devices that determine the authenticity of banknotes is vital for a banking or commercial enterprise. And this is not at all surprising, because those employees who deal with securities or cash use these devices on a daily basis. The failure of the detector can cause serious losses.
When buying this device, you should keep in mind that it will certainly require periodic monitoring of its technical condition. Complicated repair of banknote detectors is usually required in cases wherepreventive cleaning and maintenance of the equipment has not been performed by the user.
Despite the fact that by design the detectors have a large margin of safety, they suffer from paper dust and dirt, which invariably appear during operation. The garbage accumulated inside the device leads to malfunctions in its operation, as well as mechanisms and sensors break down.
The internal device of the detector consists of two parts - mechanical and electronic. The repair of the first of these is the replacement of belts, as well as the reconfiguration of various shafts and pins. In the electronic part, as a rule, the accuracy of the optical detection sensor is adjusted, as well as the elimination of breakdowns in the power supply, which may suffer due to sudden changes in electrical voltage.
The detectors of most companies producing this technique are of good quality. Device breakdowns often occur due to non-compliance with the rules of operation, as well as due to normal wear (aging) of mechanisms.
