How to Money Detector Machine Detects Fake Note


Money detectors come with optical sensors. These sensors are generally placed on top of the machine for better view. The sensor might either buzz or emit red light in case of any discrepancies. Indian notes come with computed dots that are placed with specific gaps between them.

A well-programmed optical sensor can easily detect faulty lines and gaps if the note is not genuine. It also looks through different patterns to detect what type of note has been inserted into the machine. Some sensors can also detect the composition of the notes.

Physical Elements

The thickness of a note has a lot to do with its genuineness. Currency notes are of a particular thickness. Their dimensions and thickness are all noted down by the Central Bank for checking purposes. Notes that are directly released by the Central Bank come with a clear polyester thread rooted within them.

The thread is engraved with the denominator of the note. These threads are visible only when held up in the light. Each denomination has a unique thread position which the Central Bank notes down. These threads glow in a unique color when exposed to ultraviolet rays. If it fails to do so, the money detector machine would automatically consider the note to be a forfeited one.

GMR Sensor

Currency notes come with magnetic elements in them. They are magnetized along the direction of the magnetic array. These magnetic elements are infused with the ink used on the notes.

Therefore, the signature of the governing body has magnetic elements in it. A money detector can easily identify any discrepancies made to the inked magnetic field. Any changes to the ink would result in a reversed signature.


Another feature that is used by the money detector to identify a genuine note is a watermark. Every note or coin comes with a watermark. Watermarks are so convenient as they help in minimizing counterfeiting.

Currency notes generally come with digital watermarks. These watermarks are not visible to a plain eye. But a money detector would easily identify them. Any misleading would mark them as forfeited.

How to Choose a Money Detector Machine?

Before you buy a money detector machine, you should look at the below-mentioned features. These features would ensure that you have invested in the best money detector for your business or company:

Prompt sensor

A sensor has a very important role in money detection. If you end up buying a machine with a faulty detector, you would not identify fake notes or bills. Therefore, you must look for a detector that would buzz or beep whenever in contact with forfeited notes.

Billing time

You should ensure that the machine you invested in can accommodate large amounts of notes. This would save hours of toil from your side. The more notes it can identify, the better are your chances of proceeding with other work.

Intuitive Interface

When in a hurry, we often tend to make silly mistakes. For example, we might insert two notes together in the machine. A money detector should easily detect such problems. A detector with a good interface would automatically indicate such problems. It would reject the extra note from entering the machine.

Incandescent Light

As mentioned above about the unique watermarks that notes carry, a money detector should have the feature of incandescent light. This means that once the note is placed under this light, the watermark would be visible to plain eyes.

This way, you would be able to identify whether the note is genuine or fake. The machine would automatically reject a note without a watermark. Often error codes are visible on the LED of the detectors for better understanding.

Magnifying glass

A money detector with a magnifying glass makes the procedure easy. It would help the user to identify any hidden watermarks or imprints. A note generated by Central Bank would not have any other imprints other than the ones already mentioned by Central Bank itself. These discrepancies would allow the user to immediately take action against the one using such notes.

The article above is divided into 4 important divisions for your understanding of how to use a money detector machine. You must invest in a good money detector. It would help you to identify any divergences from the guidelines mentioned by the Central Bank. You need to know about the operations performed by the machine and the features that you should look for while investing in one.

The list is curated especially for your benefit. You can also take a cue from other online sources. Consultations with authentic mart owners or businessmen would be beneficial too.
