The Discover Card is a credit card issued primarily in the United States, but Discover is also issued in limited form internationally through network partners. Capital One Financial Corporation completed its acquisition of Discover Financial Services on May 18, 2025.
We receive relatively few complaints about Discover. The most common problems are with disputes. Check out our guide to credit card disputes for strategies on handling a chargeback.
Discover’s customer service response times can vary depending on the method of contact, the volume of inquiries, and the nature of the issue.
Discover offers a built-in cash back rewards program across its credit cards, with no annual fee. Cardholders earn 5% cash back on rotating quarterly categories (up to $1,500 in spending each quarter when activated) and 1% on all other purchases. A standout feature is the first-year cash back match, where Discover doubles all the cash back earned at the end of the first year — though the program is relatively basic, lacking travel perks or purchase protections found on other rewards cards
