Credit cards can be extremely useful. If you have little or no credit history, you can use a credit card to build good credit. Credit cards are also used like cash and accepted almost anywhere. Unlike cash, however, every time you use a credit card, you're borrowing money from a lender. When the lender doesn’t receive the full amount that is owed or the payment is late, your credit can be affected.  

Good and bad credit directly affects your ability to access credit cards. If your credit is low, you will have a lower credit limit, higher interest rates and higher fees than someone with better credit. Or you may have problems even being approved for a credit card. If you're having a tough time resolving your credit problems, contact a legitimate credit counselor.

When you pay your credit card balance in full and on time every month, it will help improve your credit rating. And good credit gives you more access to make purchases on a home, a car and other loans. 

However before you choose a credit card, it's important to know what you’re getting. Be sure you shop around for the best terms and avoid the pitfalls.
