What is QR code and how does it work?
QR codes are very common these days, providing people with a convenient way to share information. These black-and-white squares are widely used in restaurants and stores, as well as on all kinds of print advertisements. The QR code is short for “Quick Response Code,” and these simple codes have become a useful tool in the smartphone era.
The QR code was released in 1994 by a Japanese company called Denso Wave. However, the research that went into the QR code’s development dates back to the 1960s. During that time, barcodes were becoming widespread in Japanese supermarkets. However, barcodes had some limitations. The biggest problem was that barcodes could not contain as much information as people would like. After becoming aware of the problem, Denso Wave’s development team created a new two-dimensional code that suited the needs of the public better, and this became known as the QR code.
QR codes can be scanned from any angle and can contain much more information. They were first used in Japan’s automotive and shipping industries. With the invention of camera phones, the application of QR codes has expanded globally.
