Segment Reporting [Abstract]  
Segment Disclosures Segment Disclosures
The Company manages its business activities in two segments: Digital Banking and Payment Services.
•Digital Banking: The Digital Banking segment includes Discover-branded credit cards issued to individuals on the Discover Network and other consumer products and services, including private student loans, personal loans, home loans and deposit products. The majority of Digital Banking revenues relate to interest income earned on the segment’s loan products. Additionally, the Company’s credit card products generate substantially all revenues related to discount and interchange, protection products and loan fee income.
•Payment Services: The Payment Services segment includes PULSE, an ATM, debit and electronic funds transfer network; Diners Club, a global payments network; and the Company’s Network Partners business, which provides payment transaction processing and settlement services on the Discover Network. The majority of Payment Services revenues relate to transaction processing revenue from PULSE and royalty and licensee revenue from Diners Club.
The business segment reporting provided to and used by the Company’s chief operating decision-maker is prepared using the following principles and allocation conventions:
•The Company aggregates operating segments when determining reportable segments.
•Corporate overhead is not allocated between segments; all corporate overhead is included in the Digital Banking segment.
•Through its operation of the Discover Network, the Digital Banking segment incurs fixed marketing, servicing and infrastructure costs that are not specifically allocated among the segments, except for an allocation of direct and incremental costs driven by the Company’s Payment Services segment.
•The Company’s assets are not allocated among the operating segments in the information reviewed by the Company’s chief operating decision-maker.
•The revenues of each segment are derived from external sources. The segments do not earn revenue from intercompany sources.
•Income taxes are not specifically allocated between the operating segments in the information reviewed by the Company’s chief operating decision maker.
