When a customer held their QR code in front of the kiosk camera, the kiosk could sometimes read the same code several times and repeat the check-in. Each scan is now read only once.
- A QR code held up to the camera is read once, even if the camera briefly loses sight of it.
- The same code can be scanned again after it has been moved away from the camera for a moment.
- The next customer's code is still read straight away.
