Practical guide
How can a menu be updated without reprinting its supports?
The QR code must point to a stable address while the menu content remains editable. Update the affected products, publish and then scan an existing support. Generate a new QR code only if the public address itself changes.
Why can the support remain unchanged?
If the encoded public URL stays available, server-side content can change without altering the printed pattern. A code aimed directly at a temporary or versioned file is more likely to become obsolete.
What update process should be followed?
- Identify the exact change.
- Review effects on allergens and translations.
- Edit and publish.
- Scan an existing support.
- Inform front-of-house if the served offer changed.
When is a new QR code required?
- The public address changes without a durable redirect.
- The original code contains an error.
- The destination becomes private or is deleted.
- The physical support is no longer readable.
