QR codes

QR codes, or Quick Response codes, are two-dimensional barcodes that store information in a grid of black squares on a white background. Scannable by smartphones and other camera-equipped devices, QR codes can contain various types of data, such as URLs, contact information, text, or payment details. They are widely used for quick access to online content, marketing, contactless payments, and other applications requiring fast and efficient data transfer.
