Controlled banknotes placed on the translucent window 4. Through a magnifying glass 10 monitor the condition of the watermark pattern and paper in transmitted white light. Small fragments bill see through the short-focus area 16 bifocal magnifier 10, while they are visible with a significant increase. An overview of the entire banknote is carried out through long-focus zone 17 bifocal magnifier 10. The operator manipulates the position of the banknote relative to the focal planes magnifier to achieve various visible growth, thus providing the optimal control bill in transmitted white light.

Then controlled banknotes through a wide slit 3 is placed on the lower table 2. Using the handwheel 8 UV filter 7 is installed in a vertical position. With the ez Lupu 10 monitor the condition of the watermark, drawing and paper in reflected white light. The operator manipulates the position of the banknote relative to the focal planes magnifier to achieve various visible zoom, providing the optimal control bill or its fragments in reflected white light. Changing the angle of the banknote relative to the line of observation, the operator controls the banknote in sliding beams. Thus, the control of the sliding beams with small angles of incidence on the device operate in the same area, bottom of table 2.

Next, using the handwheel 8 UV filter 7 is installed in a horizontal position. Through a magnifying glass 10 is controlled fluorescence banknote excited by ultraviolet radiation. The operator manipulates the position of the banknote relative to the focal planes magnifier to achieve various visible zoom, allowing optimal control of fluorescent zones bill, including protective fiber.

Based on the comparison of the results of observation of the controlled banknote with the visual standard genuine banknote, the operator judges the authenticity of the controlled banknote.

Rability control bill, located on the bottom of table 2, is only possible when the source 14 of white light.

Thus, the proposed device allows for comprehensive control of authenticity of documents, as in the control examines the various signs of authenticity both in transmitted and reflected white light and ultraviolet irradiation. Bifocal magnifier at the top and bottom position, forming an enlarged image of the banknote or its fragments, provides increased reliability of the control. The presence of the inclination of the bottom of the table and translucent Windows, and holes to enter the note on the bottom table provide ease of use and ergonomics. The presence of one control zone on the lower table provides the compactness of the device. The use of the device in the classroom conversion can significantly increase the quality of expertise and thus reduce the cost of the examination cash tickets.
