A third form type joins Registration and Transfer Ownership: Product Feedback, so anyone scanning a tag can tell you what they think of the product.
Create a form, pick the Product Feedback type, add questions, drop a Submit button and publish. Attach it to an experience through the Product feedback form slot in Experience Settings, then add a Button block with its action set to Product Feedback.
No login is required, unlike registration, and a captcha check shows before the form to prevent spam. If the person is logged in, the submission is attributed to their account; if anonymous, it is saved without one.
Submissions are stored as form answers linked to the scanned digital ID. If a feedback button shows but nothing happens on tap, the experience most likely has no feedback form attached — check Experience Settings. Test before publishing: open the experience, tap the button, solve the captcha, submit, and confirm the success page shows.
