Consumer warnings highlight risks of revolving credit cards

Credit cards can serve as useful financial tools when used responsibly, offering benefits such as credit building and expense management. Effective use depends on understanding key concepts like billing cycles, payment deadlines, and avoiding interest charges by paying the full balance each month.

The Spanish consumer organization OCU warns specifically against revolving credit cards, citing their high commissions and interest rates that can turn modest debt into costly, long‑term obligations. OCU advises consumers to compare total annual costs, consider alternative products such as debit, standard credit, or prepaid cards, and to keep multiple cards to match different needs while avoiding perpetual debt accumulation.
