How QR Codes Work

QR codes, short for Quick Response codes, are two-dimensional barcodes that can store a variety of information. They work by encoding data such as URLs, text, contact details, or other information into a matrix of black squares on a white background. These codes are designed to be easily scanned and decoded by QR code readers, which are readily available on most smartphones and devices.

QR codes work by representing data using patterns of black and white squares, which are arranged in a grid. The position and arrangement of these squares determine the encoded information. QR code readers use their camera to capture the QR code's image and interpret the pattern to extract the data it contains. This data can then be used to open a web page, display text, save contact details, or perform various other actions.

QR codes have become an essential tool for businesses and individuals, enabling quick and convenient access to digital content and information. Their versatility and ease of use make them a popular choice for applications like marketing, ticketing, and inventory management.
