QR Codes for Menus, Events, and Campaigns: What Works
2026-05-09
Sizing, contrast, and destination URLs—practical tips before you print or share a QR code.
Use HTTPS links where possible and test the scan on more than one phone before mass printing.
Ensure enough quiet space around the code and strong contrast; blurry or tiny codes fail in the wild.
Prefer short, stable URLs or landing pages you can update, so printed materials stay valid after campaigns change.
For Wi‑Fi or vCard payloads, double-check the exact string format your generator expects.
