Credit and debit cards are a "cashless" way to pay for goods and services. Debit cards take money from an existing bank account. Credit card payments are a form of a loan from a bank and must be repaid.
This category is for INFORMATIONAL credit card and debit card sites. Intent is the key here. If the intent of a site is to inform about rather than make money off of credit card applications, then it _might_ get a listing. If the site has some _original_ essays or information then the chance of a listing improves.
"Comparison" sites must NOT be linking to "apply now" pages for their collection of offers. Those sites are affiliate-linked credit card malls and NOT informational sites. DO NOT BOTHER submitting such sites. They won''t be listed.
