With a secured card, your credit limit is set based on a cash deposit you pay to the lender. A balance transfer credit card is a traditional unsecured credit card that offers an introductory rate for balance transfers, for example, 0% APR for 15 months, so cardholders won’t pay interest during that period. They will just pay a balance transfer fee. . Balance transfer credit cards are ideal for debt consolidation but are only available for borrowers with good credit.
