A QR Code is a matrix barcode (or two-dimensional code), which was created by Toyota subsidiary Denso-Wave in Japan in 1994, readable by QR scanners, mobile phones with a camera, and smartphones. The code consists of black modules arranged in a square pattern on a white background. Also, colors and images can also be added to standard black-and-white QR codes.
The information encoded can be text, a URL or other data. Without typing search words or a URL (Uniform Resource Locator) in the browser, the QR code allows us to acquire information in real time with simplified accessibility, quick response times and accuracy.
