A store credit card, also called a store card or retail credit card, is a credit card issued by a bank in partnership with a retailer and marketed under the retailer's brand. The Consumer Financial Protection Bureau uses the term for two products. A private label card is "linked to an open-end, revolving credit account that can only be used at one merchant or a few retailers related to a common brand or holding company," and carries the retailer's branding but not a major network's. A retail co-brand card is a general purpose card that carries the retailer's branding and "can be used at a wide variety of merchants by transacting over a network."
The distinction matters more than the shared name suggests. A private label card is closed-loop: it is useful only for buying from that retailer, and because it does not run on a network it generates almost no interchange income. The CFPB's 2023 report on the credit card market gives that as the reason private label issuers "do not typically fund rewards via interchange income." A co-branded card behaves like any network card, with rewards or perks tied to the sponsoring retailer.
