Discover's official website provides the ability to check a card balance online. Users must first register their Discover account on the website in order to login and access account information.
In addition to account balance information, users can set up alerts and reminders, schedule automatic payments, check recent purchases, download statements and manage reward points. There is also a spending analyzer tool that categorizes purchases and helps track spending habits over time.
To access a card balance from a smart phone, Discover offers a mobile app for both iOS and Android. Another option for accessing a Discover card balance online is Mint.com, a personal finance application that tracks multiple credit card and banking accounts. Once the user is registered, Mint displays balance and account information directly from Discover.
