Despite the ever-increasing possibilities, as well as the advantages of electronic circulation of money supply when making a variety of settlements, the use of cash is still present and is carried out at the discretion (at will) of the client (buyer, customer). At the same time, such a payment scheme is often welcomed, but has a significant drawback - the possibility of receiving counterfeit banknotes (banknotes), which:
- Not accepted by banks for exchange.
- Confiscated by law enforcement agencies on the basis of obvious signs of a serious crime (counterfeiting banknotes).
It will be almost impossible to compensate or partially compensate for the losses. A guaranteed preventive solution to this problem is magnetic currency detector , with the help of which an employee accepting payments in cash will easily detect a fake and perform the necessary actions according to the internal instructions (call the guard, activate the alarm, announce the alarm).

The natural question of a practical user: "How trustworthy is this device and what have magnets to do with it if the banknotes are paper?" - it is quite natural and understandable. So, in order:
- Almost all banknotes are coated with special dyes.
- The dyes contain metal-containing pigments.
- In addition, banknotes can be equipped with visible or hidden metal threads that make up a single whole with the texture of the paper.
The use of a classical electromagnet in currency detectors, including ATMs, allows detecting the presence of a given composition of paint and protective metallized elements, thus confirming the authenticity of the verified bill.
As a rule, modern magnetic currency detectors are additionally equipped with ultraviolet sensors to clearly view the presence (quality) of watermarks. You can get acquainted with a wide range of detectors using the website of the company that supplies this type of equipment to the domestic market.
