QR Code Guides
Everything you need to design, print, and deploy reliable QR codes.
QR codes look simple on screen, but reliable deployment depends on error correction, quiet zones, contrast, file format (PNG vs SVG), and whether the payload is static or redirect-based. These guides explain how matrix codes work and how to avoid unscannable print runs.
Articles cover structure and standards, sizing for viewing distance, WiFi and vCard payloads, logo placement, outdoor signage, analytics hooks, and security considerations when codes appear in public spaces. Use them alongside the QR Code Generator and QR Scan tools while you iterate.
Comparing QR to retail barcodes? Read QR vs barcode when packaging needs both consumer scans and POS stripes.
QR Codes for Outdoor Signage
Billboards and sidewalk signs need larger modules and high contrast for distance scanning.
QR Codes and Mobile Deep Links
URL QRs can open app store pages or in-app destinations when deep links are configured.
Tracking QR Code Scans
Static codes do not report scans by themselves — track via unique URLs or redirects.
Common QR Code Mistakes
Missing quiet zones, low contrast, and undersized modules cause most field failures.
Testing QR Codes Before Print
Verify artwork with phone cameras and, when possible, the scanners your venue uses.
