What Is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that stores data in a grid of black and white squares. Invented in 1994 by Denso Wave in Japan, QR codes can be scanned by any smartphone camera to quickly access URLs, contact information, or other data.
Error Correction Levels
- Low (L) — 7% data recovery. Smallest QR code, best for clean environments.
- Medium (M) — 15% recovery. Good default for most use cases.
- Quartile (Q) — 25% recovery. Good for printed materials.
- High (H) — 30% recovery. Best for harsh environments or when adding a logo overlay.
