How QR Codes Store Information
Quick Response (QR) codes are two-dimensional barcodes invented by Denso Wave in 1994. They feature built-in Reed-Solomon error correction that enables successful decoding even if up to 30% of the barcode is obscured or damaged.
Guidelines for Print and Display
- Maintain high contrast (dark modules on light background).
- Leave a quiet zone of at least 4 modules around the outer border.
- Keep URL payloads short to avoid dense, unreadable matrices.
