In today's digital world, we do many things online. From sharing contacts to digital payments and even document verification, everything is done digitally. QR codes have played an important role in making all these tasks easier. While making UPI payment, you just have to scan the QR code and you can make payment easily.
The specialty of the QR code is that it becomes unique every time it is generated; that is, every QR code is different from each other. Do you know that the QR code was invented about 31 years ago? Yes, the technology of QR codes that we use today for everything from UPI payment to Aadhaar verification was invented 31 years ago.
QR or Quick Response Code was invented by a Japanese engineer Masahiro Hara in 1994. Masahiro has graduated from Hosei University of Japan. 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.
When Masahiro Hara saw this game board, he thought that a lot of information could be stored in a grid and that 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 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.
