How to use a promo code?

If you have received a promo code, navigate in the app to the menu by pressing 'More'. Go to 'Payment' and click on your current payment method. Here you find the option to 'Add promo code'. Just enter or paste the code and choose 'Redeem code'.

Now your extra parking credit is visible in the previous screen. Before you start a parking, the credit will also show on the parking screen.
