To pay with your prepaid card, you have to top it up first with the money you need. That way, you only spend the available balance. You can top it up as often as you like at no cost. Top up your card on the app, bbva.es, at BBVA ATMs, branches or by calling 900 102 801. Choose an amount between €6 and €6,000 (€1,000 if it is for the Aqua card). This money will be added to the card balance.
