At the moment it’s possible to add or save a PayPal account to your profile in the hvv switch app. You can either create a new PayPal account by closing the app first, or you can add an existing PayPal account. All you have to do is follow the instructions shown the first time you make a booking using the hvv switch app. Once a PayPal account has been set up for your hvv switch profile, you can make changes to your settings at any time. This includes replacing it with a different PayPal account.
You won’t be able to delete your payment method entirely because it's absolutely essential for using hvv switch. Therefore you can change the payment method, but you can't delete it. If you want to delete it entirely, you need to terminate your hvv switch account.
