The importance of product choice

Ultraviolet wavelengths can be divided into UVA(320~400nm), UVB(280~320nm), UVC(100~280nm). The wavelengths capable of verifying forgeries are UVA wavelengths.

When purchasing a UV LED Detector, it is important to double check the UV LED’s quality. The results can be significantly affected depending on which UV LEDs are used.

One of the following currency bills is a forgery. Can you tell which bill is a forgery? As you can see, the quality of the paper and printing conditions are very similar, making it is impossible to distinguish which bill is forged using the naked eye. How will the two bills change when viewed under ultraviolet light to uncover which one is forged?

1) Low-price UV LED Detector(test product made by us for research purposes)

The currency bill was verified using the low-price UV LED Detector. Fluorescent security features are visible in identical spots on the front of the bill. Except for the fact that the top bill has slightly blurry security features, it is almost impossible to distinguish which bill is a forgery.

2) MP12t

The currency bill was verified using our MP12t product. Although fluorescent security features are visible in identical spots on the front of the bill, they are of a different color. The fluorescent security fibers on the bottom bill are clearly visible whereas the one on the top is not visible at all. The top bill is a forgery.

It is possible to verify the existence of security features using the low-price UV LED Detector. However, they should not be used to determine is a currency bill is real or forged based on the mere fact that security features exist. Using machines that cannot distinguish between the colors of fluorescent security features or detect the existence of color fibers poses as risk and makes them extremely suitable for use when identifying forgeries.
