Match the QR to the goal
Use URL QR for landing pages, WhatsApp QR for inquiries, location QR for directions, and payment QR for immediate payment.
Make it large enough
Flyers can use smaller codes than posters, but both need enough size and quiet space for easy scanning.
Add a call to action
Tell people why to scan: get coupon, book now, view menu, join event, or save contact.
Use stable campaign links
Point the QR to a campaign page you control, then update the page content if the offer changes.
