If you are trying to build credit, then revolving credit is a great place to start. You may have seen advertisements for credit cards such as Capital One secured cards, or credit one bank, etc. Depending on your FICO Bankcard scores you will be assigned a lower limit if under 640. You can get $300 credit limits, but the truth is that you want to show high revolving credit limits. The below cards report as revolving accounts, and have higher credit limits $3000-$5000. The best on the list is My Jewelers Club. They report to all three bureaus, where Hutton Chase and Ox Publishing only to report to one or two bureaus. New Coast Direct only reports to 2 bureaus however will also give a $5000 limit.
