What Is a Credit Card Issuer?
Credit card issuers are financial institutions that offer, approve and manage credit card accounts. These include banks, credit unions and financial technology companies. Your issuer will serve as the lender for the money used when you make purchases using your credit card.

A cardholder owns a credit card by being in contract with the credit card issuer and agreeing to specific terms and conditions.
