A balance transfer credit card is a type of credit card that allows you to move existing debt from one or more credit cards to a new card, often with a lower interest rate. This can help you save money on interest payments and pay off your debt more quickly. Many balance transfer cards offer an introductory period with 0% interest, making it easier to manage your finances. To use a balance transfer credit card effectively, you typically need to apply for the card and then request the transfer of your existing balances. Be aware of any fees associated with the transfer, as well as the interest rate that will apply after the introductory period ends.
