When you arrive at the car park entry, ensure you have driven all the way up to the entry boomgate. After making sure your car is stationary, open the Shuffle App and tap the Open gate button. If the car park has multiple entry lanes, the app will prompt you to select the lane you are in.
If the bluetooth function does not connect or is taking too long, click on Use QR Code. Once the QR code is displayed, place your phone about 5cm away from the QR code reader on the entry column to open the gate.
