Fiserv, Inc.
Registration Statement on Form S-8

Dear Sirs:

I have acted as counsel for Fiserv, Inc., a Wisconsin corporation ("Fiserv"),
in connection with its Registration Statement on Form S-8 (the "Registration
Statement"), filed under the Securities Act of 1933 (the "Act"), relating to
the proposed sales of up to 4,100,000 shares of its Common Stock, $.01 par value
(the "Shares"), pursuant to the Fiserv, Inc. Stock Option Plan.

In that connection, I have examined originals, or copies certified or otherwise
identified to my satisfaction of such documents, corporate records and other
instruments as I have deemed necessary or appropriate for purposes of this
opinion, including the Articles of Incorporation, as amended, and By-Laws, as
amended, of Fiserv.

Based upon the foregoing, I am of the opinion that:

1.   Fiserv has been duly organized and is validly existing as a corporation
under the laws of the State of Wisconsin.

2.   The Shares have been duly authorized and are validly issued and fully paid
and nonassessable.

I hereby consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference to me under "Legal Matters'' in the Information
Statement comprising a part of the Registration Statement.  By giving the
foregoing consent, I do not admit that I come within the category of persons
whose consent is required under Section 7 of the Act.

Very truly yours,


/S/ CHARLES W. SPRAGUE
Charles W. Sprague
Executive Vice President,
General Counsel and Secretary
