QR codes turn offline attention into measurable online actions. For small businesses, that means turning posters, packaging, receipts, and even uniforms into clickable links—without a keyboard. This guide shows you how to deploy QR codes effectively, design them for maximum scan-rate, and measure ROI.
What should your QR code do?
- Claim offer / coupon: Send scanners to a landing page with an exclusive discount.
- Menu or product catalog: Perfect for restaurants, salons, and boutiques.
- Review link: Deep-link to Google Maps or your review platform.
- Follow / subscribe: Link to Instagram, TikTok, newsletter, or SMS club.
- Contact / booking: Open a prefilled contact form or scheduling page.
Best placements for more scans
- Front door & checkout: Loyalty sign-ups, Wi-Fi join, or receiptless warranties.
- Packaging & inserts: “How-to” videos, recipes, upsells, or review requests.
- Outdoor posters & vehicle wraps: Event RSVP or “find us” directions.
- Tables & counters: Menus, tip jars, and feedback forms.
- Business cards & flyers: vCard, portfolio, or “book now.”
Design for scan-ability
- Size: As a rule of thumb, make the code at least 2.5 cm (1 inch) square for arm’s-length scanning. For posters, go larger.
- Contrast: Dark modules on a light background scan best. Avoid low-contrast pastels.
- Quiet zone: Keep some empty space around the code so cameras can find edges.
- Logo overlay: Fine—just increase error correction (Q or H) and don’t cover the “finder eyes.”
- Test on phones: Always test on both iOS and Android default cameras.
Track your results (without creepy tracking)
Create a unique URL for each placement so you can measure scans by location. E.g., use UTM parameters like ?utm_source=door&utm_medium=qr. Privacy-friendly and effective.

Bottom line
With smart placement and simple tracking, QR codes can reliably drive store visits, orders, and reviews. Start small, test placements, and double down on what gets scans.
