QR codes deserve the same care as signs and links
A QR code can send a phone to any encoded destination, including a malicious one. The U.S. Federal Trade Commission has warned that scammers can cover legitimate QR codes with their own. For restaurants, the practical response is straightforward physical and digital hygiene.
Use a recognisable destination
Where possible, send guests to a domain or menu address associated with your business or a trusted provider. Add a short printed URL near the QR so customers have context about what should open.

Inspect physical codes
A replacement sticker placed over a table QR can be hard to notice. During cleaning or opening checks, look for peeling edges, unexpected stickers, damage or signs that a code has been covered.

Secure the account that controls the menu
Use a unique strong password and enable multi-factor authentication when the service supports it. Limit administrator access to people who need it and remove access promptly when roles change.
Keep devices and software current
Phones, browsers and management devices benefit from current security updates. If the menu runs on your own website, keep the application, server and dependencies maintained as well.
Know your expected URL
Staff should know the legitimate menu domain. If a scan suddenly opens a different hostname, login prompt, download or payment request that does not belong there, take the code out of service and investigate.
Be careful with third-party redirects
Dynamic QR services can be useful, but they become part of the trust chain. Understand who controls the redirect and what happens if the subscription or account changes.

Respond quickly
If tampering is suspected, remove affected signage, verify the real destination, reset relevant credentials if needed and replace the physical code. Then check other QR placements rather than assuming the issue is isolated.
Your menu can change. Your QR doesn't have to.
Create a clean mobile menu, publish it and keep updating the content behind the same QR.
