100 Yuan What do the 29 dots on the front mean?

The 29 points on the front of RMB 100 are anti-counterfeiting rings.

Those small circles are found on coins in many countries. They are just the latest anti-counterfeiting technology. The name is EURion constellation, which is also called anti-replication ring and Omron ring.

Orion, also known as anti-copy circle and Omron ring, is a symbol pattern found around 1996, which is used in many banknote designs. They are added to the pictures of banknotes to help graphic software, printers and copying equipment detect banknotes. This software will prevent users from printing or copying images with EURion constellation symbols, thus preventing people from forging banknotes through color copiers. The world's major currencies, such as the US dollar, the euro and the Japanese yen, have all joined this symbol rule.

The People's Bank of China tried this technology on the 1999 RMB 1 yuan banknotes issued in 2004, and the anti-copying effect was good. In the updated version in 2005, this technology was completely adopted.
