Comparison Pro Intellect NC 1300 vs DoCash 430

Means for authenticity check of counterfeiting or damaged bills, provided in the design of the detector.

— Ultraviolet(UV). Detection based on the illumination of bills with ultraviolet light. Many modern currencies have protective elements in their design that glow under such light. Also, with UV light inscriptions made with special varieties of “invisible ink” become visible (for example, the inscription “Bribe” on bills used as evidence in a criminal case). Due to its simplicity (only a UV lamp is required for operation), this type of detection is very popular and is found even in inexpensive devices.

— Infrared(IR). Detection using infrared light. It is similar in application to ultraviolet (see above), except that a special camera and display are needed to view bills in IR light. Therefore, detectors with this function are usually not cheap.

— By size. An authenticity check that involves determining the size of a bills. It can be used both to check for authenticity and to detect foreign bills in a stack of bills of the same denomination, as well as to search for torn, folded in half, worn out money. Usually, such check is effective only if there are noticeable differences between suspicious bills and the regular.

— By magnetic marks. Authenticity check based on the reading of magnetic marks.... Such tags are used in many modern currencies (in particular, US dollars and euros), mainly in the form of a special paint that is “noticeable” for magnetic sensors.

— By optical density. Detection based on optical density — the ability of a bills to transmit and retain light. It is mainly used in automatic detectors (see "Product Type") to detect sticky bills: the device reacts to a significant excess of optical density.

— Check in white transmitted light. Verification based on translucence of the bills with white visible light. Usually, such translucence is used to develop watermarks, security stripes and other similar elements, as well as to assess how the image on different sides of the bill correlates.

— Check in white reflected light. A check based on the analysis of the reflection of white light on the surface of the bill. Illumination with bright white light allows you to identify some security features (eg holograms), as well as evaluate the quality of printing security, print clarity, security fibers, etc.

— Ink spectral analysis. Spectral analysis of the ink that was used to apply the pattern allows you to determine its chemical composition based on the characteristics of the reflected light. In this way, you can detect a counterfeit even if all other security elements are indistinguishable from the original ones.

— Special element "M" verification. The special element "M" is a label that is clearly visible in infrared light only when illuminated with infrared light of a certain wavelength. The detection of this element is carried out due to the fact that the detector alternately illuminates the bills with IR rays with different wavelengths, due to which the effect of the label “flickering” occurs on the detector screen.

— Anti-stokes verification. The special element "I" (also known as "anti-stokes") is applied using a special composition, which begins to glow, under the intense infrared light of a certain range. At the same time, unlike the special element “M” described above, this glow can be seen with the naked eye; it may have different colours.

The speed of the autofeed system provided in the design of the counterfeit detector.

Such a system is a mandatory element of any automatic model (see "Product Type"). Note that not every similar detector allows you to charge a stack of bills and automatically process them one by one — usually the autofeed system is only responsible for pulling a bill through the detector, and you need to load bills one by one manually. Therefore, with the speed of auto-feeding you can evaluate not so much the performance of the counterfeit detector (it also depends on the user's skills), but the time spent on processing one bill. For example, a 120 bills/min device will spend 60/120=0.5 s for each bill.

— Display. The availability of its own display in the design of the counterfeit detector. Such displays can be roughly divided into two types. The first is the simplest screens that display service information in text form: for example, the number of bills checked, current settings, battery charge, etc. The second variety are displays where the user can view the bills being checked. Such displays can provide zoom image, and also allow you to see elements that are inaccessible to the naked eye — for example, the special element "M" (see "Authenticity Check"). The specific functionality of the display in both cases may be different.

— Built-in magnifying glass. The availability of a built-in magnifier — a magnifying glass — in the design of the counterfeit detector. This device facilitates the verification of small details on the bills being checked. At the same time, magnifiers are noticeably simpler, cheaper and more reliable than specialized displays, but their capabilities are much more modest. Therefore, such equipment is found mainly in the simplest detectors.

— Video mouse. A video mouse is a device designed to control the image on the counterfeit detector's display: it allows you to move, as well as zoom in and out the image. Thanks to this, it is possible to examine in detail individual parts of the bill being checked without moving it relative...to the camera.

— Sound indication. The presence of a sound indication system in the design of the counterfeit detector. In this case, we mean a system that beeps when a suspicious bill is detected. Due to this, the probability of missing such a bill is reduced to almost zero.

— Auto power off. The availability of the auto-off feature in the design of the counterfeit detector. The meaning of this feature is described by the name itself: if the switched on device is idle for some time, it automatically turns off to save power consumption. This is especially important when using built-in or rechargeable batteries (see below) that have a limited charge.

The total power consumed by the counterfeit detector during operation. In most cases, this parameter is purely reference. Even the most powerful modern counterfeit detectors consume about 50 – 60 W — this is not enough to overload the network or significantly increase power consumption. However, there are situations where power data can be useful, such as when calculating the load on an uninterruptible power supply.
