The second thing that you should be looking for is the introductory rate. Credit cards all offer introductory rates; however, these rates are not going to stick around for long. What you want to look for is how long they will stick. A credit card that offers 0% interest for a full year is a wonderful deal, and can be a great way to save some money while you pay down a large charge. Keep in mind, though, that the rates for new charges and the rates for balance transfers are different! If you are looking to transfer a balance, then a good deal for balance transfers is much more important than a good rate on new purchases.
Rewards programs are also a good thing to look for, since so many credit card companies offer them. It is a shame to make purchases and not get cash back when so many cards will offer you a percentage of your money back in rewards. Keep in mind, however, that if the rates are not good, then you will spend more money in interest than you will earn in rewards, making it a moot point.
If you love reward cards, then be sure to pay the balance in full each month. This allows you to earn rewards on your purchases but at the same time allows you to keep your debt from accruing interest or from growing larger, which can benefit you quite a bit. It is actually good policy, in any case, to pay your balance in full every month.
Another thing to keep in mind is that some stores may not accept every card. Discover cards, for example, while widely accepted, are not accepted everywhere. If you have a particular store or location in mind for use of your card, make sure that this location either takes all cards, or that it at least takes the kind of card for which you are applying.
The right credit card for you might also come in a more obvious package. Student credit cards, for example, are specifically designed to be easily accessible to college students. These can be much easier to get (and to use for buying those necessary books), even if you are a student with no existing credit. Business credit cards offer bonuses to small business owners, and can be helpful to you if you own a business.
Choosing the right credit card, in many cases, comes down to paying attention to the advertising to get the real details, and to spending the time that it takes to track down a really great offer.
