Constellation currency name and shape _ Constellation currency name and shape picture

In the upper right corner of the front watermark and the upper right corner of the back watermark, there are some irregularly arranged small circles, some say it is anti-counterfeiting, some say it is braille, and some say it is decoration.

These circles are called "Omron constellation", and the Chinese name is circle constellation anti-counterfeiting technology, which was invented by Omron Corporation of Japan and enjoys patent, so it is also called "Omron ring". Omron ring consists of five small circles arranged in the shape of Orion.

Omron ring is a pattern that can prevent high-precision color copier. In the color copiers produced now, the recognition of this pattern is preset. Once the pattern containing this constellation is found, the copier will automatically output it, which will cause serious color distortion or not output it directly. Drawing software like Photoshop has its own "EURion constellation recognition" program. Personal computers and digital imaging tools can be prevented from obtaining or copying images of protected banknotes. Although there are so many circles on the RMB, there are not many that can really form Omron rings, usually only one, and the remaining circles are obstacles to disguise Omron ring patterns.

Not only the RMB, but also the world's major currencies such as the US dollar, the euro and the Japanese yen, as well as Canada, Egypt, Japan, Norway, Mexico and Singapore. Australian banknotes combine Omron rings into a flower; Omron ring and another number together constitute the denomination of money on different denominations of dollars.

I wonder if it is wonderful to see RMB. In our life, we often encounter counterfeit money. You can verify the authenticity of money by Omron ring.
