Registration to the Flowbird service is free.
Just create your account on my.flowbirdapp.com or via the Google playstore (Android) or Apple IOS (iPhone) applications.
Register the license plate number of the vehicle you are to park.
During your first Flowbird transaction, you will enter your debit/credit card information, which is stored securely so you never have to enter it again. When you select and purchase a parking transaction with Flowbird, you pay the standard parking fee charged by the parking operator (private operator, local authority, University, Hospital etc) within the location you are parking, plus an additional convenience fee for use of the Flowbird service to purchase your parking session. You will be notified of the total parking transaction fee prior to you confirming your payment and the start of your paid parking session.
