In fact, this kind of design is not superfluous, nor is it full of food, nor is it used for decoration. This design is an anti-counterfeiting technology for RMB. This anti-counterfeiting technology was first developed by the Japanese company Omron. Therefore, since this company owns the ownership of this patent, this technology is also named Omron Ring internationally. In my country's RMB, the widespread use of Omron rings was first triggered by the RMB in 2005.
In 2004, our country introduced this technology and began to use it. The earliest period was in 2005, when it was printed on the 1999 edition of one yuan. After practice, we found that the effect of this was very good, so we chose to widely apply this technology to the 2005 edition of banknotes. This is why we usually see small circles on the RMB.
As for the use of Omron ring technology, it is actually not only available in our country, but also many countries in the world have adopted this technology. The purpose is to prevent counterfeiting of currency. It can be said that Omron is still a very advanced technology in currency anti-counterfeiting technology. But although when we look at the RMB, there are many small circles on it. But the really useful Omron is composed of five small circles. And they are combined according to the arrangement of the Orion constellation.
So these small circles are not used for decoration in the simple sense as we imagine, and if we observe these small circles carefully, if they are used as decorations, they are not very decorative. It looks good, and for those with obsessive-compulsive disorder, it seems a bit superfluous! It can be said that every part of the RMB is not added out of thin air and has its own meaning. So far, Omron rings are a very ideal anti-counterfeiting technology.
