Keep the task simple
For a review stand, the useful outcome is opening the correct review page. Keep the printed instructions short and the physical stand within reach.
Test compatibility
Try the tap with the phones available to your business and check the QR fallback too. The phone may ask the customer to open the link. Customers control their own device and review.
Keep information private
A public review page should not contain private customer information. A link on a stand is not a certification of a business or of privacy compliance.
