Set a limit per transaction. Whenever a purchase is above that limit, it’ll be declined and we’ll alert you.
Setting a spending cap helps you keep on top of your spend. There's flexibility to access money if you change your mind.
You can apply a gambling lock to each of your eligible cards. This will automatically block most gambling transactions.
