The common QR Code was first invented by Tenghongyuan of Japanese company Denso Wave in 1994. And transformed from the original bar code, compared with the bar code data storage capacity is greatly improved. The first two-dimensional code is color, which is mainly used to track the maintenance of its auto parts. Later, on this basis, in order to improve work efficiency, Denso Wave Company improved the common black and white today. But the first product to be bar-coded was Wrigley gum.
on QR code, different regions represent different information. Generally speaking, the QR code has become an indispensable part of life. It does bring a lot of convenience to our life.
We in China also have our own QR code: "Hanxin Code". Its inventor is Wang Yue, CEO of Yirui Technology, and cooperated with China Item Coding Center to complete the design and development of Hanxin Code.
Hanxin code looks somewhat similar to QR code, but for us in China, there are many optimizations. Its current design language is Chinese, which is equivalent to supporting all Chinese, and it is the only code system that fully supports the 183 coding level. Moreover, its Chinese character identification efficiency is also the highest at present. In other words, it can represent more information of Chinese characters with less area, which can provide more convenience in application.
More importantly, Hanxin Code is the only QR code with completely independent intellectual property rights in China. It has been applied to some application fields involving information security, such as tax anti-counterfeiting, product traceability supervision, etc. For example, Hanxin code is expected to become the standard code system in China's invoice field. Moreover, Hanxin code is also on the way to international standardization, and will soon be released as a formal international ISO standard. It is foreseeable that we will see more and more Hanxin codes in our lives.
