The short answer
Use a QR code when it removes a real step for the recipient—booking, requesting an estimate, viewing a portfolio, opening a menu, reading reviews, or saving contact information. Do not add one simply because there is room. The destination should be mobile-friendly, the printed card should explain what the scan opens, and the final customized code must be tested before ordering.
A QR code needs one clear job
A useful code connects the physical card to the next action. The destination should match what someone is most likely to do immediately after meeting you.
Explain the destination in print
Use a short cue such as “Scan to book,” “View our work,” or “Request an estimate.” A bare code asks the recipient to guess and provides no fallback when scanning is inconvenient.
- Keep a printed phone number or website
- Use strong light-dark contrast
- Protect quiet space around the code
- Avoid placing the code over texture or photography
Test after every meaningful edit
Test the exact final preview with more than one phone, from a realistic distance, and on the destination’s mobile page. Re-test if the URL, code image, color, size, or surrounding layout changes.
