How do QR codes actually work? 🤨 📱 QR codes work by encoding data (like website links, text, or contact info) into a pattern of black and white squares, read by a smartphone camera, which decodes the pattern into binary (1s and 0s) and performs the associated action, like opening a URL or app. Key parts include large "finder patterns" for orientation and alignment markers for distortion correction for clear definition, allowing for quick data storage! #science #physics #engineering #technology
