The first place to look for credit card fine print is on the back pages of your paper statements. You can also find the agreements on your issuer’s site thanks to the Credit Card Accountability, Responsibility, and Disclosure (CARD) Act of 2009. Look for tiny links or different symbols used as footnotes when evaluating online offers.
The Consumer Financial Protection Bureau also maintains a database of different credit card agreements – credit unions included.
If you can’t find complete terms and conditions for any reason, ask a representative from your credit card company.
