POWER OF ATTORNEY

     Know all by these presents that the undersigned hereby constitutes and

signing singly, the undersigned's true and lawful attorney-in-fact to:

          (1) execute for and on behalf of the undersigned, all reports to be
filed by the undersigned pursuant to Section 16(a) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and the rules promulgated
thereunder (including Forms 3, 4 and 5, and any successor forms) (the "Section
16 Reports") with respect to the equity securities of Discover Financial

          (2) do and perform any and all acts for and on behalf of the
undersigned that may be necessary or desirable to complete and execute any such
Section 16 Reports, complete and execute any amendment or amendments thereto,
and file such report with the U.S. Securities and Exchange Commission and any
stock exchange or similar authority; and

          (3) take any other action of any type whatsoever in connection with
the foregoing that, in the opinion of such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall

     The powers granted above may be exercised by each such attorney-in-fact on

fiduciary or representative capacity in which the undersigned may be acting.

     The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or

hereby ratifying and confirming all that such attorney-in-fact, or such

attorney regarding the purposes outlined herein as of a later date.
