Since the great recession banks have become much more strict in approving credit cards. It is more difficult for those with bad to fair credit to get approved for a credit card.
The easiest credit card to get approved for will be a secured card. These are specifically created for those whom are trying to rebuild their credit. They work by putting up a security deposit and you will then be able to spend up to that amount. Many use secured cards after having charge-offs or bankruptcy.
