An introductory offer, sometimes called a teaser rate, is offered by credit card companies as a way of getting you to sign up with their card by offering a very low interest rate. What most people don’t know is that the rate is only temporary, and eventually the rate will go up, as soon as you begin using the card, or after you transfer the balance from your old card to the new card. So, be skeptical when presented with these offers and read the fine print. If you are still curious, call and speak to a representative.
