How QR Codes Work
QR (Quick Response) codes store data in a two-dimensional barcode that can be scanned by any smartphone camera. They were invented in 1994 by Denso Wave for tracking automotive parts, but are now used everywhere — from restaurant menus to payment systems.
Our generator creates QR codes entirely in your browser. No data is sent to any server, so your information stays private. The generated codes follow the ISO/IEC 18004 standard and include error correction, meaning they can still be read even if partially damaged.
