How many credit card offers do you receive in the mail? By now, you are probably numb to the message and only consider switching credit cards or adding a new one based on an event like a hefty renewal fee or nasty interaction with a credit card issuer's automated phone system.

For those considering a switch, a study by Keynote Systems ranks credit card company websites in areas like ease of use, service, privacy, and security.

We've included the two leaders from the Keynote study, Chase and Bank of America, as picks in the Credit Card Issuers category in the Moneysmartz Directory. We particularly like Chase for its high customer service rating.
