Essential QR Code Best Practices

  • Test before printing: Always scan your final QR code with both an iPhone and an Android phone under real lighting before mass printing.
  • Preserve the quiet zone: Never crop out the white margin surrounding your QR code; cameras need this padding to recognize code boundaries.
  • Keep dark colors on light backgrounds: Inverting colors (white QR on black background) causes scan failures on some older camera sensors.
