A QR code, or Quick Response code, is a two-dimensional matrix barcode that stores information in a visually readable pattern of squares.
It can encode various types of data, such as website URLs, contact information, or product details.
QR codes are widely used for quick and convenient information retrieval, often scanned with a smartphone or other QR code reader devices.
They are employed in marketing, ticketing, inventory management, and contactless payment systems, making them a versatile tool for linking physical objects to digital content or actions.
