A practical workflow
Lead with identity
Use the familiar business name and a readable logo. Keep the product branding secondary to the place the customer visited.
Write a neutral caption
Tell customers they can share their experience. Avoid asking for a specific star rating or promising a reward.
Keep the scan area clean
Place one QR on the card and leave enough space around it. Test the card at its final print size.
Avoid this mistake
Do not place payment and review QRs together without unmistakable labels.
What to check
Ask a customer which action the card offers before they scan it.
Test the whole physical journey
Check both the printed code and the page behind it. A successful scan is only the entry point: the customer still needs to recognise the business, describe an experience and understand the Google handoff. Use the final material under ordinary lighting. Keep a copy of the approved artwork so a replacement does not accidentally introduce a different destination.
