Who created the QR code?

QR or Quick Response Code was invented in 1994 by Japanese engineer Masahiro Hara. Masahiro has graduated from Hosei University in Japan. This code was developed by Denso Web, a subsidiary of Toyota Motor Corporation. Masahiro Hara got the idea of ​​a QR code while playing the Go game. If you have never played a Go game, then let us tell you that it has a Go board, which has a 19×19 grid. This grid consists of black and white stones.

A lot of information is hidden in the grid.
When Masahiro Hara saw this game board, he thought that a lot of information could be stored in a grid and it could be read from many angles, distances, etc. After this, Masahiro, along with the Denso web team, worked to convert this grid system into a QR code. This QR code contains data for locator, identifier, and web tracking. It was first used to label parts in the automobile industry. Later it started being used for many things including electronic tickets, contact sharing, payment.
