QR code is a matrix-type two-dimensional code that expresses information by arranging white and black cells in a grid pattern. Based on a development philosophy focused on the field of use, the code was developed with emphasis on enhanced reading performance, such as all-direction high-speed readability, resilience against smudges and damage, and resistance to distortion of the code. Thus far, this code continues to evolve. In addition to the excellence of the code, we are proud of the fact that we declared the code public domain to be used freely without exercising patent rights and worked to popularize it, i.e., the behavioral style of photographing the code with a camera and accessing information. This code has had a huge impact on society, creating new lifestyles, such as payment methods, ticket gates, and entrance methods to venues, thereby inducing changes in the behavior of people. The Japan Society for Management Systems recommends the QR code, which originated in Japan and has become popular globally, for its Kototsukuri-Collection.
