Collecting interest is how a lender makes its money. While it is not in a bank's best interest to issue "interest free" credit cards, most do extend such offers for limited periods of time. For example, a lender might extend an offer for a card that is interest-free for 12 months. After that, the lender hopes the cardholder will keep and use the card though it would then have interest. So while you may be able to secure an interest-free card, it won't always be interest-free. The best way to avoid interest on a credit card is to pay it off each month.
