Only a specially trained bank employee is able to correctly check a bill for authenticity. But ordinary citizens also need to have basic skills in identifying counterfeit banknotes.
Instructions
Step 1
Check out the signs of authenticity of banknotes. Use only official sites for this, since the rest of the information can be deliberately distorted by counterfeiters in their own interests. Below are the addresses of such documents with descriptions of the signs of authenticity of rubles, US dollars and euros:
Step 2
Purchase a device for determining the authenticity of banknotes: ultraviolet, magnetic, infrared, translucent. Some of them are combined and, taking up less space on the table, replace several devices at once. The most widely used devices are those that combine the functions of ultraviolet, magnetic, and transmission detectors. They are much more convenient to use with built-in lenses and a ruler. But such a device must be supplemented with one more separate one - infrared.
Step 3
Use two switches to operate the combined appliance. One of them, located on the back of the main unit, turns on the power of the device, and the magnetic sensor, if present, also starts working. The second, located on the shade with ultraviolet lamps, allows you to select the mode: ultraviolet (UV) or transmission (PE).
Step 4
When checking a bill with ultraviolet light, first pay attention to the glow of the paper. It shouldn't be there at all (compare with ordinary office paper, which glows bright blue under the detector lamp). However, if there is one, this does not mean that the bill is fake - it could well have ended up with the trousers in the washing machine, and the bleach from the powder was transferred to it. For an exact answer to the question whether the banknote is genuine, contact the bank. But those areas that, according to official documents, are covered with a phosphor, should glow, and both the color and the shape of the luminous pattern must fully correspond to the exemplary ones. If, in addition to the official ones, there are extraneous glowing marks, the bill may have been marked and was previously used during an operation to catch criminals. In this case, it will not hurt to check it with an ordinary dosimeter, since sometimes during such operations banknotes are marked not only with phosphors, but also with radioactive substances.
Step 5
When checked for light, the watermarks should be clearly visible. Pay attention to the conformity of their form and location with those shown in the official documents. The method of obtaining watermarks has not been secret for a long time, but the work of counterfeiters is hampered by the fact that the special drum required to obtain them has very large dimensions and cost.
Step 6
To check a banknote on an infrared detector, place it under the illuminator and camera, and observe the image on the monitor. Compare the shape and location of the infrared marks with the reference ones.
Step 7
To check for the presence of invisible magnetic stripes, slide the corresponding section of the bill over the magnetic head of the device. There should be a sound accompanied by LED flashes. Also make sure there are no magnetic stripes where they should not be.
Step 8
Match the size of the bill and its individual elements with the official ones using the ruler built into the device.
Step 9
Do not forget about those signs by which a bill can be checked without instruments (paper crunch, diving threads, paint that changes color depending on the viewing angle, etc.). Always check their presence and compliance with those described in official documents, even if there are devices. If you have any doubts about the authenticity of the banknote, please contact the bank.
