Understanding QR Code Technology

Quick Response (QR) codes are two-dimensional barcodes that store information in a machine-readable optical format. They can encode various types of data including URLs, contact information, WiFi credentials, and plain text.

Error Correction Levels:

Low (L) ~7%

Minimal error correction. Best for clean environments with high-quality printing.

Medium (M) ~15%

Balanced error correction. Good for most general use cases and standard printing.

Quartile (Q) ~25%

Higher error correction. Suitable for industrial or harsh environment applications.

High (H) ~30%

Maximum error correction. Best for small QR codes or damaged surfaces.
