The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan.[5][6][7] The initial alternating-square design presented by the team of  researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board;[8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3:1:1) in black and white areas on printed matter, which cannot be misidentified by an optical scanner.[9][5] The functional purpose of the QR code system was to facilitate keeping track of the types and numbers of automobile parts, by replacing individually -scanned bar-code labels on each box of auto parts with a single label that contained the data of each label. The quadrangular configuration of the QR code system consolidated the data of the various bar-code labels with Kanji, Kana, and alphanumeric codes that were printed onto single label.[10][9][5]Japan

As of 2024, QR codes are used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile-phone users (termed mobile tagging). QR codes may be used to display text to the user, to open a webpage on the user's device, to add a vCard contact to the user's device, to open a Uniform Resource Identifier (URI), to connect to a wireless network, or to compose an email or text message. There are a great many QR code generators available as software or as online tools that are either free, or require a paid subscription.[11] The QR code has become one of the most-used types of two-dimensional code.[12]

During the month of June 2011, 14 million American mobile users scanned a QR code or a barcode. Some 58% of those users scanned a QR or barcode from their homes, while 39% scanned from retail stores; 53% of the 14 million users were men between the ages of 18 and 34.[13]

In 2022, 89 million people in the United States scanned a QR code using their mobile devices, up by 26 percent compared to 2020. The majority of QR code users used them to make payments or to access product andNot a valid attachment ID.

Nowadays, QR digital payment become ubiquitous, and will become future norm.
So when a Digital QR payment company goes public,  we invest a certain amount to  purchase it's share, in next 10 years, one or two company will become super huge, their share price will bloated thousand fold,  few will bust, and a few will be swallowed up by the successful company.
This strategy works, because we can't predict future, the only certain, is ONE or TWO will become SUPER HUGE.
