About QR Codes
QR (Quick Response) codes are two-dimensional barcodes that can store URLs, text, contact info, Wi-Fi credentials, and more. They were invented in 1994 by Denso Wave for tracking automotive parts and are now used everywhere from restaurant menus to boarding passes.
- Error correction allows the QR code to remain scannable even if partially damaged or obscured. Higher levels mean more redundancy but a denser (larger) code.
- Color contrast matters for scannability. Keep high contrast between foreground and background. Dark foreground on light background works best.
- Size affects print quality. Use 800px or 1200px for printed materials, 200-400px for digital use.
- Data capacity in byte mode: L=2,953 chars, M=2,331 chars, Q=1,663 chars, H=1,273 chars (at version 40).
L 7% recovery
M 15% recovery
Q 25% recovery
