The QR code (二维码) has become an important part of our lives. But have you ever wondered who invented the QR code?
In the 1960s, supermarkets began to appear in Japan. Cashiers had to put the price of each product in the computer by hand. It was really hard work.
Later, the bar code (条形码) came out and solved the problem. It made its users' work easier, but there was a new problem: the bar code could just hold a little information. So, many developers started to improve the bar code. Masahiro Hara was one of them. He thought, “With the bar code, information is coded in one direction only. With a 2D code, information can be coded in two directions: across and up down.” So, Hara set out to develop a new 2D code holding a large amount of information. To make it be read as fast as possible, he made the code black, white and square.
In 1994, Hara's QR code came out. The QR means quick response (反应). It was soon used by a car company and later in the food industries. It was such a success that Hara could use it to get plenty of money, but he didn't. He made it public so that everyone could use it freely. “The more people use it, the more new ways of using it there will be. I think this is why the QR code was born,” Hara says.
