Go to brobizz.com “Update payment card”, where you need to provide your 16-digit bizz number and your customer number.
If Öresundsbron has issued your bizz, click https://www.oresundsbron.com/sv/kundservice/mitt-konto.
Please note that it may take up to 24 hours before your new payment card is registered and the bizz is updated.
If you forget to update your payment card, the bizz will be blocked and you will need to buy a new ticket at the terminal. It is not possible to have the amount refunded afterwards.
