Why QR codes matter for small businesses
QR codes let customers jump straight to a menu, landing page, or payment info with a single scan from their phone camera — no app install, no typing a long URL.
1. Use a high error correction level when adding a logo
When placing a logo in the center of a QR code, choose error correction level H (30%) so the code still scans reliably even with part of it covered.
2. Don't shrink the QR code too much
The recommended minimum print size is about 2 x 2 cm (0.8 x 0.8 in). A code that's too small makes it hard for cameras to focus, especially on printed materials or stickers.
3. Check the color contrast
The background and foreground colors need clear contrast. A light background with a dark code (or vice versa) always scans more reliably than similar tones placed together.
4. Always test before printing in bulk
Scan the QR code with several different devices and camera apps before printing large quantities, so you don't end up reprinting everything if the code fails.
5. Use dynamic content when it changes often
If your menu or promotions change frequently, point the QR code to an editable landing page instead of embedding static content directly into the code.
