QR Code Use Cases

QR codes bridge the physical and digital worlds. Common use cases:

• Marketing materials — link print ads, posters, and business cards to landing pages
• Product packaging — link to setup guides, warranty registration, or reorder pages
• Events — link attendees to schedules, maps, or feedback forms
• Restaurants — digital menus (popular since 2020)
• WiFi sharing — encode WiFi credentials so guests connect without typing a password
• vCard — share contact details that can be saved directly to a phone
• Payment — link to payment pages or crypto wallet addresses

QR Code Best Practices

Error correction levels:

• L (7%) — small, suitable for clean print environments
• M (15%) — good balance for most uses
• Q (25%) — for branded QR codes with logo overlay
• H (30%) — maximum redundancy, required if a logo covers 30%+ of the code

Size recommendations:

• Business card: 2×2 cm minimum
• Flyer/poster: 3×3 cm minimum
• Billboard: scale proportionally to viewing distance

Always test on multiple devices before printing. A QR code that doesn't scan wastes every print run.

QR Codes in Automation

QR codes can trigger automation workflows when scanned — logging product scans, triggering CRM record creation, or initiating form pre-fills. This is a common pattern in GoHighLevel-based marketing automation, where a scan can kick off an entire follow-up sequence. Book a consultation to discuss QR-triggered automation for your business.
