FIserv, Inc.
Registration Statement on Form S-3

Dear Sirs:

          I have acted  as counsel to  FIserv, Inc., a  Wisconsin
corporation  ("FIserv"),  in  connection  with  its  Registration
Statement on Form S-3 (the "Registration Statement"), filed under
the Securities Act of 1933 (the "Act"), relating to the  proposed
resales of up to 1,033,900 shares  of its Common Stock, $.01  par
value (the "Shares"), by  certain Selling Stockholders  following
consummation of the proposed  acquisition (the "Acquisition")  by
FIserv of  all  the  outstanding  capital  stock  of  Information
Technology, Inc.

          In that  connection,  I  have  examined  originals,  or
copies certified or otherwise  identified to our 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.  The Company 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,  upon
consummation of the Acquisition, will be 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 Prospectus 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,

CHARLES W. SPRAGUE
