Discover is a credit card brand issued primarily in the United States. It was introduced by Sears in 1985 and currently issued by Capital One. Discover was the first credit card that did not charge an annual fee and offered a higher-than-normal credit limit. A subsequent innovation was "Cashback Bonus" on purchases.
Most cards with the Discover brand are issued by Discover Bank, formerly the Greenwood Trust Company. Discover transactions are processed through the Discover Network. In 2005, Discover Financial Services acquired Pulse, an electronic funds transfer network, allowing it to market and issue debit and ATM cards. In February 2006, Discover Financial Services announced that it would begin offering Discover debit cards to other financial institutions, made possible by the acquisition of Pulse.
Discover is the third largest credit card brand in the U.S., with 60.6 million cardholders or about 8% of cards in circulation, placing it well behind Visa (48%) and Mastercard (36%), but slightly ahead of American Express (7.5%).
