      Re:  Registration Statement on Form S-8

Ladies and Gentlemen:

      We  have  acted  as  counsel  to  Euronet  Worldwide,   Inc.,  a  Delaware
corporation  (the "Company"),  in connection with the Registration  Statement on
Form S-8 (the  "Registration  Statement") filed with the Securities and Exchange
Commission (the  "Commission")  by the Company on or about the date hereof under
the Securities Act of 1933, as amended (the "Act").  The Registration  Statement
relates to 4,000,000 shares of the Company's  common stock,  $0.02 par value per
share (collectively,  the "Shares"),  to be issued by the Company under its 2006
Stock Incentive Plan ("Plan").

      In connection  therewith,  we have relied upon,  among other  things,  our
examination of such  documents,  records of the Company and  certificates of its
officers and public  officials as we have deemed  necessary  for purposes of the
opinions expressed below. We express no opinion as to matters under or involving
the laws of any  jurisdiction  other  than  the  corporate  law of the  State of
Delaware and the federal law of the United States of America.

      For  purposes  of the opinion  expressed  below,  we have  assumed (i) the
authenticity of all documents submitted to us as originals,  (ii) the conformity
to  original  documents  of  all  documents  submitted  to  us as  certified  or
photostatic  copies  and the  authenticity  of the  originals  and (iii) the due
authorization,  execution  and delivery of all  documents by all parties and the
validity,   binding   effect  and   enforceability   thereof   (other  than  the
authorization, execution and delivery of documents by the Company). This opinion
assumes that the provisions of the Company's  Certificate of Incorporation  will
not be amended after the date hereof.

      Based upon and subject to the foregoing,  and having regard for such legal
considerations  as we have deemed  relevant,  assuming  that upon  issuance such
shares  together with all shares of Common Stock  previously  issued or reserved
for issuance and not duly and lawfully retired do not exceed 90,000,000  shares,
and  assuming  that the  consideration  paid for such shares  complies  with the
applicable  provisions of the Delaware General  Corporation Law and the Delaware
Constitution  regarding the

form and amount of  consideration  required for valid issuance of capital stock,
upon the issuance and sale of said 4,000,000  shares for the  consideration  and
upon the terms and conditions set forth in the Plan, said shares will be legally
issued, fully paid and non-assessable.

      We hereby  consent to the filing of this opinion with the Commission as an
exhibit  to the  Registration  Statement  and the  reference  to our firm in the
Registration Statement.

      We do not undertake to advise you of any changes in the opinions expressed
herein from matters that might hereafter arise or be brought to our attention.

                                Very truly yours,

                                STINSON MORRISON HECKER LLP
