Types of authenticity check with certain signs on the money being counted and provided in the design of the counter. Only models for paper money are equipped with detection (see “Product Type”).
—
By size. A detection that involves determining the size of a bills. In bill counters, usually, it is used for sorting by face (see "Functions") or dilapidation, but it can also be used for other purposes — for example, identifying bills that are not related to the currency being counted.
—
By optical density. Detection based on optical density — the ability of a bills to transmit and retain light. It is mainly used to detect sticky bills and prevent counting errors, but can also be used to screen out worn or suspicious bills.
—
By magnetic marks. Detection based on the reading of magnetic marks. Typically, such marks are applied with a special paint, "noticeable" for magnetic sensors; note that they are widely used in US dollars and euros. This type of detection can be used both to determine the denomination and to separate bills in other currencies and detect counterfeit bills.
—
Ultraviolet (UV). Detection using UV radiation. Devices with this feature are able to detect special security elements that are visible only under ultraviolet light, and respond to the absence or non-standard arrangement of s
...uch elements. Due to this, it is possible to detect not only counterfeit or foreign bills, but also money marked with special compositions (for example, bills used as material evidence in a criminal case on a bribe and signed respectively). However, if the possibility of identifying marked bills is fundamentally important for you, its availability should be clarified additionally.
— Infrared (IR). Detection using infrared radiation. By the operating principle, it is similar to the UV detection described above, however, protective IR elements are less common, and their detection is technically more difficult. Therefore, this detection function is found mainly in hi-end devices, in particular, high-precision sorters (see "Product Type").Availability of the
remote display bill counter package.
Such a display, usually, duplicates the readings of the main screen installed on the body. The most common way to use this feature is to install a screen in front of the customer, for example, near the checkout window; this allows the client to control the data received by the cashier when counting bills. However, the remote display can also be useful to the operator — for example, if the counter had to be installed in an uncomfortable place where the device's own screen is barely visible.
