What is a QR Code?

QR Codes are a form of two-dimensional barcode that can store a large amount of information. They consist of black modules arranged in a square pattern on a white background. These codes were originally developed by the Japanese company Denso Wave in 1994, and since then, they have become widely used in a variety of applications. One of the main attractions of QR Codes is their ability to store different types of data, including URLs, text, contact information, and even commands to perform specific actions on a mobile device.
