Your BroBizz® only works, if it is associated with a valid credit or debit card. That is why it is important to update your details, when you change your debit/credit card or fuel card.
You can update here
If you wish to use a credit card or a debit card it is very easy to update. All you need is your new credit/debit card, your BroBizz number and your postal code. If you wish to use af fuel card, you will have to log into My Account and change it there.
