This code was developed by Denso Web, a subsidiary of Toyota Motor Corporation. Masahiro Haro got the idea of ​​QR code while playing Go game. If you have never played Go game, then let us tell you that it has a Go board, which has a grid of 19x19. This grid has black and white stones. 

A lot of information is hidden in the grid.

This QR code contains data for the 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, and payment.
