How to choose a banknote detector? Which firm of the banknote detector is not worth buying
At present, the probability of meeting a counterfeit bill 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 apparatus and the principle of their operation.
Means of protection of currency
The banknote detector is now a mandatory attribute of any credit institution, financial structure and many outlets. This is easily explained by the fact that no one wants to receive simple 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 the note could be determined only by the watermark, which was easily determined for clearance, now the degree of protection is very complicated.
First of all, in order to increase wear resistance, cotton or linen fibers are included in the composition of the bill paper. In addition to the basic tissues inside the money, there are fluorescent particles, watermarks, special elements, embossing, fibers, microprinting, combined drawing, perforation, protective threads, kinegrams and holograms, and zones of infrared protection.
The banknote detector is a machine that scans bills and compares the information received with a programmed standard. In the event of a mismatch of at least one of the parameters, the device sends a signal to the operator. It can also reject a counterfeit bill by placing it in a special pocket.
Instrument types
All existing banknote detectors are divided into two types. The first of these include viewing devices (ultraviolet and infrared, as well as complex). The second type of detector is automatic.
The viewing devices allow you to clearly see the unobtrusive or hidden signs of the authenticity of the moneymark. However, the final decision must be made by the operator. As for automatic detectors, they independently select fake bills, excluding the human factor. This is especially true in cases when workers are of low qualification. If an automatic detector is used, the cashier may not be trained to detect fakes. Fake banknotes through the device will not pass.
Ultraviolet detectors
Such devices have only recently stood in almost every outlet. The banknote authenticity detector is equipped with a special lamp. It works in the ultraviolet mode. UV rays, hitting the bill, cause its fibers to glow in different colors.
Today such detectors have become practically useless. Counterfeiters have already acquired the skills of forging this component of protection. Despite this, ultraviolet detectors continue to enjoy stable demand. This is explained by the following:
1. Very low cost, starting from 100 rubles. A well-forged fake such a detector will not reveal. However, there is still a point in finding it at the outlet. The mere fact of having such a device in the hall is able to scare off the beginning distributors of counterfeit notes. But experienced fraudsters will go to this store.
2. The presence of this device is necessary for the sale of alcohol at the request of the licensing chamber. On this apparatus, excise stamps are checked.
3. Ultraviolet devices are often purchased by veterinarians. They need them to identify depriving 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 with a power of 6 watts. This powerful source of ultraviolet rays can effectively recognize fake banknotes in a well-lit room. The lower lamps serve to check the watermarks, microperforations, as well as images on the two 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, accuracy located on the banknote of labels, etc. This device is quite simple to operate.
Such a model will also help in the event that it becomes necessary to clarify the authenticity of the document. To do this, use a special slot available on the back of the case.
Infrared Detectors
Today, this type of device for the recognition of counterfeit money is most in demand. The infrared detector of banknotes guarantees the identification of counterfeits. Scammers have not yet learned how to make such money on their money.
The design of this device is quite simple. The cashier has the test bill in front of the detector, which shows through its infrared LEDs. The rays are reflected from the banknote and pass through the light filter. Then they are captured by the camera, displaying a picture of the bill on a special display. The cashier sees the bill in the infrared range. On a genuine currency, only a small fragment of his picture is clearly visible. The fake lights up all. An experienced cashier is able to quickly check a whole stack of money by flipping bills in front of the detector.
With the help of such a device, it is possible to check the authenticity of various documents in which there is IR protection. These are securities, passports, etc. Infrared devices are used in the cash desks of not only retail outlets, but also of various large companies.
Popular model
Infrared detectors of DoCash Mini banknotes are very in demand. They occupy minimal space, are equipped with a desktop stand of innovative development, which reinforce the ribs. The design allows you to securely install the device and exclude its tilting. In addition, the device will not slide on the table, since it has rubber feet.
Detectors of banknotes DoCash Mini can easily be installed in minibuses, cars or in a taxi. This will significantly reduce the risk of payment for services by fakes. Often, these detectors can be seen at the banks' offices, at service enterprises, at retail outlets, etc. The device is advantageous for its small size and large screen, which lacks optical distortion. It attracts users simplicity of its design and simple control, understandable on an intuitive level. It is also convenient that the device can be powered not only from the mains, but also from the battery.
Complex devices
Such a banknote detector is able to check all existing types of money protection. In this unit, IR and UV devices are combined into one housing. In addition, complex detectors provide for:
- lower conventional and very good upper backlight;
- a test pencil;
- magnetic head (checks magnetic marks of banknotes).
There are other options. That's why these devices have impressive sizes. Not the lowest price they have.
Banks must have complex detectors. Only in this case they will be able to test different types of money protection. Is it worth having such a device trading organization? Hardly it is necessary to overpay for the device which will not be used on all hundred percent. But the choice is always for the buyer.
The popular model of the expert complex
Detectors of DoCash Big D banknotes combine the capabilities of IR and UV devices. They are equipped with the functions of complex visual control of the protective features of not only money, but also securities, as well as documents, etc.
Detectors of banknotes DoCash Big D carry out the following types of control:
- elements of images applied by IR-colors;
- the general background and individual fragments of images;
- special paints, in which anti-Stokes luminophores are present, glowing with infrared radiation in red and green;
- Special Element "M";
- geometric dimensions;
- Bills in white passing, reflected, and also falling obliquely.
The camera of such a detector gives a ten- and twenty-fold increase in the image of the bill.
Automatic Detectors
The use of devices of this kind does not require special knowledge from the operator. Authentification of banknotes such a detector performs in automatic mode. These devices are used where there is a need for frequent and rapid checks of bank notes.
Automatic banknote detector is installed in the supermarket and store cash departments, at gas stations and in banks. Such devices will equally qualitatively verify the authenticity of any currency.
Automatic banknote detector determines the quality of the bill immediately through several elements of protection. 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 quite easy to operate. User reviews confirm that the cashier is enough to insert a bundle of notes into the hole. The whole apparatus will do the rest of the work itself. He counts the banknotes, while checking them for authenticity.
Dors Bills Detector
This is a simple and easy-to-use automatic device. For example, the Dors 220 banknote detector can be used to check money of all years of issue and all denominations. The model is released in a modern ergonomic design and has compact dimensions. This device has reliable detection, high speed of verification (seventy-five bills per minute) and a large resource. It is convenient and easy to operate.
The banknote detector Dors 220 can operate in two modes. In the first of these - basically - the original bill goes through a special slot on the output, and the counterfeit goes back to the receiving stream. In case of detection of a fake, the device displays a message on the screen that says about the detection error. For convenience, this data may have a sound.
The second mode of operation is designed to operate the device in a confined space. The machine returns all the notes to the receiving tray, reporting a detection error with an audio signal and a recording on the display.
The Dors 220 detector has the advantage of having unimpeded access to the path. This option is available thanks to the flip cover. In addition, the device is equipped with a system that allows the user to adjust the power saving mode by means of auto power off after a certain time interval. The detector has a multilanguage menu and the ability to configure inverse display of information on the screen. Such a device can be connected to a computer, using it in working with the program for a cash register.
A difficult choice
Any organization working with cash should be equipped with devices to determine their authenticity. Reliable and convenient in operation currency detectors are original protectors of business. And portable versions of such devices to business people are desirable to have with them always.
Repairs
Elimination of the breakdown of devices that determine the authenticity of notes is vital for a banking or commercial enterprise. And this is not surprising, because those employees who deal with securities or cash, use these devices daily. The failure of the detector can cause serious losses.
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 cases when the user did not perform preventive cleaning and maintenance of equipment.
Despite the fact that the design of 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 the fact that in its work there are malfunctions, as well as mechanisms and sensors break down.
The internal structure of the detector consists of two parts - mechanical and electronic. Repair of the first one is a replacement of belts, as well as the reconfiguration of various shafts and pins. In the electronic part, as a rule, adjustment is made for the accuracy of the optical detection sensor , as well as for eliminating the breakdown of the power supply unit, which can suffer due to sudden changes in the voltage.
The detectors of the majority of firms that produce this equipment are of good quality. Breakage of devices is often due to non-compliance with the rules of operation, as well as due to normal wear and tear (aging) mechanisms.
