- How does Discover monitor my account for fraud?
We monitor every purchase on your account every day. If a purchase looks unusual or suspicious, we let you know with an e-mail, text message or phone call from our U.S.– based Fraud Specialist team. If you have an unauthorized purchase on your account, we remove it. Because you're never responsible for unauthorized purchases on your Discover card account - guaranteed. And we can even overnight a new card to you for free at your request.
- How does Discover protect my information?
Discover uses technology and physical protection measures to help safeguard your personal information. That includes technology controls to help protect your information from outside hacks as well as business controls to help prevent unauthorized access. And of course, it means security guards, locks and passkeys at all our offices.
