How dynamic QR reduces risks

Dynamic QR reduces the time a capture can be used. It is an additional operational layer, not a replacement for Fudi's other validations.

How to protect yourself

• The code is signed and linked to the current restaurant, branch, program and version.
• Expires normally after 60 seconds.
• The presentation requests a new code every 45 seconds.
• Validation allows a short technical tolerance to avoid failures during renewal.
• Disabling the channel revokes the current dynamic codes.
• An inactive branch or a program with no activity blocks the broadcast.
• Fudi requires location to register visits and applies geofence when the branch has it configured.
• The anti-duplication window prevents the same account from accumulating another visit too soon at the same restaurant.

Opening the QR link in a browser does not register a visit. The diner must scan the current code from Fudi Rewards.
