How QR Codes Work
QR codes encode data in a two-dimensional grid of black and white modules. The pattern can be read by smartphone cameras and QR readers. Error correction data is embedded in the code, allowing recovery of up to 30% of damaged data at level H. Higher correction levels increase the QR code density but improve real-world scan reliability.
