If you have bad credit I would recommend going with the Capital One Secured credit card.
I used a Capital One Secured credit card to help re establish and improve my bad credit rating.
With a capital secured credit card you put up a deposit to secure the credit card and use the Secured Credit card like any other credit card and continue to make payments on the balance owed.
If you use your credit limit on the Capital One Secured Credit card responsibly and pay off the balance in full each time your credit rating will go up overtime.
