If I have bought a product online, do I need to take the ticket when I arrive at the car park?

No, this is not necessary. In your purchase confirmation email, you will receive an access QR and instructions on how to access the car park. You can also link your number plate to your online purchase if the car park has this type of access.
If you have any doubts, you should contact us via intercom (24h) in order to check out using the contracted product.
