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.
