Who created the QR code?
Point-of-sale technology was developed as supermarkets became more crowded and lined up.
This was a very early version of the barcode. Even so, the supermarkets did not solve the problem.
Because in the early version, only one-way coding was allowed. Similarly, a barcode could only store 20 alphanumeric characters of information.
The detailed QR code is developed by DEANSO Web Inc. It was specially developed by Masahiro Hara, the company’s chief developer.
The supermarkets contacted DEANSO Web Inc. after finding out the limit of the barcode. Hara converted the barcode from Unidirectional to 2D code.
Due to this, it was possible to keep more information in the barcode. Hara decided to square the size of the QR code because it was found to be an easily detectable shape.
Squares also helped to encode information both horizontally and vertically. When placed in a square, QR code information can be read 10 times faster than barcode.
All of these investigations were made public by DEANSO Web Inc. in 1994 without patent rights. Since then, the number of QR code users has been increasing exponentially.
