Topping up your Yonder account means adding your own money on top of your existing credit limit to increase your total spending power.
For example:
If your credit limit is £500 and you top up an additional £200, your total available spending becomes £700.
You can now make purchases or transactions up to that combined amount of £700.
When you use your card to spend, any money you’ve added to your top-up account will automatically be used first to cover those transactions. Only once your top-up balance is fully used will your credit limit be used.
