How QR Codes Work

QR codes, or Quick Response codes, are two-dimensional barcodes that store information such as text, URLs, and other data. They work by using a grid of black and white modules arranged in a square pattern to encode data. The code is read by a smartphone camera or specialized QR code reader, which interprets the pattern of modules to retrieve the stored information. The process begins when a user points their smartphone camera at the QR code; the camera captures an image of the code and sends it to an app for processing. The app decodes the image by identifying specific patterns within the grid: three squares at each corner help orient the code, while timing patterns (alternating black and white modules) assist in aligning it correctly. Once aligned, each module is read as either black (0) or white (1), forming binary data that is then translated into usable information like text or URLs. QR codes have become increasingly important due to their versatility and ease of use. They can be used for various purposes such as marketing campaigns where they direct users to websites or landing pages; in retail for quick access to product information; in healthcare for storing patient data; and even in education for providing additional resources.
