Currently, the probability of meeting a fake bill is very high. Moreover, the 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 work.
Banknote Remedies
A banknote detector is now a mandatory attribute of any credit institution, financial structure 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 fake without special equipment. If earlier the authenticity of the bill could only be determined by the watermark, which was easily determined by the clearance, now the degree of protection is very complex.
First of all, to increase the wear resistance, cotton or linen fibers are included in the composition of banknote paper. In addition to the main fabrics, money contains fluorescent particles, watermarks, special elements, embossing, fibers, micro-printing, combined pattern, perforation, security threads, cinemagrams and holograms, as well as infrared protection zones.
A banknote detector is a machine that scans bills and compares the information received with the programmed standard. If at least one of the parameters does not match, the device gives a signal to the operator. It can also reject a fake bill by placing it in a special pocket.
Types of appliances
All banknote detectors existing today are divided into two types. The first of them includes viewing devices (ultraviolet and infrared, as well as complex). The second type of detectors is automatic.
Viewers 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 fake banknotes, excluding the human factor. This is especially true in cases where employees are low skilled. When using an automatic detector, the cashier may not be trained to detect fakes. Fake banknotes will not pass through the device.
UV detectors
Such devices until very recently stood in almost every outlet. The banknote authenticity detector is equipped with a special lamp. It works in ultraviolet mode. UV rays, once on a banknote, cause its fibers to glow in different colors.
Today, such detectors have become virtually useless. Counterfeiters have already acquired the skills to counterfeit this protection component. Despite this, ultraviolet detectors continue to be in steady demand. This is explained by the following:
1. Very low cost starting from 100 rubles. Such a detector will not reveal a well-fake fake. However, it still makes sense to be at a point of sale. The very fact of the presence of such an apparatus in the hall is able to scare away beginner distributors of counterfeit bills. 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 licensed 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 ultraviolet lamps. One such device is the DoCash 531 banknote detector. The device has two upper UV lamps, each of which has a power of 6 watts. This strong source of ultraviolet rays allows you to efficiently recognize fake banknotes in a well-lit room. The lower lamps are used to check watermarks, microperforation, 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 the tags located on the banknote, etc. This device is quite simple to operate.
Such a model will help in the case when it becomes necessary to clarify the authenticity of the document. To do this, use the special slot on the back of the chassis.
Infrared detectors
Today, this type of counterfeit money recognition device is the most demanded. An infrared banknote detector guarantees the detection of counterfeits. Fraudsters have not yet learned how to make such a defense on their money.
The design of this device is very simple. The cashier has the bill being examined in front of the detector, which is visible through its infrared LEDs. Rays are reflected from the banknote and pass through the filter. Then they are captured by the camera, displaying the image of the bill on a special display. The cashier sees the bill in the infrared range. On a genuine banknote, only a small fragment of his drawing is clearly visible. The fake glows all over. An experienced cashier is able to very quickly check a whole wad of money by flipping bills in front of the detector.
Using such a device for authenticity, you can check various documents that have infrared protection. These are securities, passports, etc. Infrared devices are used at the box office of not only retail outlets, but also various large companies.

Automatic detectors
The use of devices of this kind does not require special knowledge from the operator. A similar detector performs automatic verification of banknotes automatically. These devices are used where there is a need for frequent and quick checks of banknotes.
An automatic banknote detector is installed at the box office of supermarkets and shops, at gas stations and in banks. Such devices will equally authentically verify the authenticity of any currency.
An automatic banknote detector determines the quality of a bill by several security elements at once. This is quite residual for cashiers and accountants whose work is connected with cash. Models of such devices are small in size and ergonomic design. In addition, automatic banknote detectors are very easy to operate. User reviews confirm that it is enough for the cashier to insert a bundle of notes into the hole. The device will do the rest of the work itself. He will count the banknotes, while checking their authenticity.

Repairs
Correcting the breakdown of devices that determine the authenticity of banknotes is vital for a bank or merchant. And this is not at all surprising, because those workers who deal with securities or cash use these devices daily. Failure of the detector can cause serious damage.
When buying this device, it should be borne in mind that it will certainly require periodic monitoring of its technical condition. Complex repair of banknote detectors is required, as a rule, in those cases when the user did not carry out preventive cleaning and maintenance of equipment.
Despite the fact that the detectors have a large margin of safety in their design, they suffer from paper dust and dirt, which invariably appear during operation. The garbage accumulated inside the device leads to the fact that in its work there are failures, as well as mechanisms and sensors break down.
The internal device of the detector consists of two parts - mechanical and electronic. Repairing the first one is replacing the belts, as well as reconfiguring the 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 damage to the power supply, which can suffer due to sudden changes in voltage.
Detectors of most companies producing this technique are of good quality. Device failures often occur due to non-compliance with the rules of operation, as well as in connection with normal wear (aging) of mechanisms.
