Credit cards are issued by a credit card issuer, such as a bank or credit union, after an account has been approved by the credit provider, after which cardholders can use it to make purchases at merchants accepting that card. Merchants often advertise which cards they accept by displaying acceptance marks – generally derived from logos – or may communicate this orally, as in "Credit cards are fine" (implicitly meaning "major brands"), "We take (brands X, Y, and Z)", or "We don't take credit cards".
