Original title: father of QR Code talking about QR Code: never thought it could be used in payment

Two-dimensional code (2-dimensional bar code) is a black-and-white figure which is distributed in the plane (two-dimensional direction) according to a certain rule with a specific geometric figure, and records the information of data symbols. A few days ago, Japanese man Chang Hong Hara, the inventor of the QR code, gave his first interview to the Chinese media in Tokyo, according to Pear Video.

Yuan Changhong said that he felt that he had developed something great and predicted that it would be widely used in industry in the future, but it was widely used among ordinary users, which he did not expect. He had no idea that the QR code would be used as a means of payment.

Referring to the "widespread use of QR codes in China," Yuan Changhong said he was happy to have access to convenient services like WeChat Pay in Japan.

Hara Changhong invented the QR code in 1994. The public data show that in the compilation of the code, the two-dimensional code skillfully makes use of the concepts of "0" and "1" bit streams that constitute the logic foundation of the computer, and uses several geometric shapes corresponding to the binary system to represent the text numerical information. automatic information processing is realized by automatic reading by image input equipment or photoelectric scanning equipment.
